gix::config::file

Struct Section

pub struct Section<'a> { /* private fields */ }

Expand description

A section in a git-config file, like [core] or [remote "origin"], along with all of its keys.

Implementations§

impl<'a> Section<'a>

Instantiation and conversion

pub fn new( name: impl Into<Cow<'a, str>>, subsection: impl Into<Option<Cow<'a, BStr>>>, meta: impl Into<Arc<Metadata>>, ) -> Result<Section<'a>, Error>

Create a new section with the given name and optional, subsection, meta-data and an empty body.

impl<'a> Section<'a>

Access

Return our header.

pub fn id(&self) -> SectionId

Return the unique id of the section, for use with the *_by_id() family of methods in gix_config::File.

pub fn body(&self) -> &Body<'a>

Return our body, containing all value names and values.

pub fn to_bstring(&self) -> BString

Serialize this type into a BString for convenience.

Note that to_string() can also be used, but might not be lossless.

pub fn write_to(&self, out: &mut dyn Write) -> Result<(), Error>

Stream ourselves to the given out, in order to reproduce this section mostly losslessly as it was parsed.

pub fn meta(&self) -> &Metadata

Return additional information about this sections origin.

pub fn to_mut(&mut self, newline: SmallVec<[u8; 2]>) -> SectionMut<'_, 'a>

Returns a mutable version of this section for adjustment of values.

Methods from Deref<Target = Body<'a>>§

pub fn value(&self, value_name: impl AsRef<str>) -> Option<Cow<'_, BStr>>

Retrieves the last matching value in a section with the given value name, if present.

Note that we consider values without separator = non-existing, i.e. [core]\na would not exist. If that’s expected, Self::value_implicit() must be used instead.

pub fn value_implicit(&self, value_name: &str) -> Option<Option<Cow<'_, BStr>>>

Retrieves the last matching value in a section with the given value name, if present, and indicates an implicit value with Some(None), and a non-existing one as None

pub fn values(&self, value_name: &str) -> Vec<Cow<'_, BStr>>

Retrieves all values that have the provided value name. This may return an empty vec, which implies there were no values with the provided key.

pub fn value_names(&self) -> impl Iterator<Item = &ValueName<'event>>

Returns an iterator visiting all value names in order.

pub fn contains_value_name(&self, value_name: &str) -> bool

Returns true if the section contains the provided value name.

pub fn num_values(&self) -> usize

Returns the number of values in the section.

pub fn is_void(&self) -> bool

Returns if the section is empty. Note that this may count whitespace, see num_values() for another way to determine semantic emptiness.
