Struct Field

pub struct Field {
    pub symbol: FieldSymbol,
    pub length: FieldLength,
}

A field within a date pattern string, also referred to as a date field.

A date field is the repetition of a specific pattern character one or more times within the pattern string. The pattern character is known as the field symbol, which indicates the particular meaning for the field.

Fields

symbol: FieldSymbol

The field symbol for the Field, which corresponds to the field’s meaning with the date pattern.

length: FieldLength

The length of the Field, which in conjunction with the FieldSymbol informs the width or style of the formatting output corresponding to this field.

Implementations

impl Field

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient Writeable implementation. However, in order to avoid allocating a string, it is more efficient to use Writeable directly.

Trait Implementations

impl AsULE for Field

type ULE = FieldULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(unaligned: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Field

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Field

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Field

This trait is implemented for compatibility with fmt!. To create a string, Writeable::write_to_string is usually more efficient.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<(FieldSymbol, FieldLength)> for Field

fn from(input: (FieldSymbol, FieldLength)) -> Self

Converts to this type from the input type.

impl From<ErrorField> for Field

fn from(value: ErrorField) -> Self

Recover a Field (unstable) from an ErrorField (stable wrapper)

impl From<Field> for ErrorField

fn from(value: Field) -> Self

Create an ErrorField (stable wrapper) from a Field (unstable)

impl Ord for Field

fn cmp(&self, other: &Field) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Field

fn eq(&self, other: &Field) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Field

fn partial_cmp(&self, other: &Field) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<(FieldSymbol, usize)> for Field

type Error = Error

The type returned in the event of a conversion error.

fn try_from(input: (FieldSymbol, usize)) -> Result<Self, Self::Error>

Performs the conversion.

impl Writeable for Field

fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>

where S: PartsWrite + ?Sized,

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.

fn write_to_string(&self) -> Cow<'_, str>

Creates a new String with the data from this Writeable. Like ToString, but smaller and faster.

impl<'a> ZeroMapKV<'a> for Field

type Container = ZeroVec<'a, Field>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<Field>

type GetType = FieldULE

The type produced by Container::get()

type OwnedType = Field

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
