Struct git_config::file::MutableValue

pub struct MutableValue<'borrow, 'lookup, 'event> { /* private fields */ }

An intermediate representation of a mutable value obtained from GitConfig.

This holds a mutable reference to the underlying data structure of GitConfig, and thus guarantees through Rust’s borrower checker that multiple mutable references to GitConfig cannot be owned at the same time.

Implementations

impl<'borrow, 'lookup, 'event> MutableValue<'borrow, 'lookup, 'event>

pub fn get(&self) -> Result<Cow<'_, [u8]>, Error>

Returns the actual value. This is computed each time this is called, so it’s best to reuse this value or own it if an allocation is acceptable.

Errors

Returns an error if the lookup failed.

pub fn set_string(&mut self, input: String)

Update the value to the provided one. This modifies the value such that the Value event(s) are replaced with a single new event containing the new value.

pub fn set_bytes(&mut self, input: Vec<u8>)

Update the value to the provided one. This modifies the value such that the Value event(s) are replaced with a single new event containing the new value.

pub fn delete(&mut self)

Removes the value. Does nothing when called multiple times in succession.
