Struct git2::ConfigEntries

source ·
pub struct ConfigEntries<'cfg> { /* private fields */ }
Expand description

An iterator over the ConfigEntry values of a Config structure.

Due to lifetime restrictions, ConfigEntries does not implement the standard Iterator trait. It provides a next function which only allows access to one entry at a time. for_each is available as a convenience function.

Example

// Example of how to collect all entries.
use git2::Config;

let config = Config::new()?;
let iter = config.entries(None)?;
let mut entries = Vec::new();
iter
    .for_each(|entry| {
        let name = entry.name().unwrap().to_string();
        let value = entry.value().unwrap_or("").to_string();
        entries.push((name, value))
    })?;
for entry in &entries {
    println!("{} = {}", entry.0, entry.1);
}

Implementations§

source§

impl<'cfg> ConfigEntries<'cfg>

source

pub fn next(&mut self) -> Option<Result<&ConfigEntry<'cfg>, Error>>

Advances the iterator and returns the next value.

Returns None when iteration is finished.

source

pub fn for_each<F: FnMut(&ConfigEntry<'cfg>)>(self, f: F) -> Result<(), Error>

Calls the given closure for each remaining entry in the iterator.
