Struct Body

Source
pub struct Body<'event>(/* private fields */);
Expand description

A opaque type that represents a section body.

Implementations§

Source§

impl<'event> Body<'event>

Access

Source

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.

Source

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

Source

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.

Source

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

Returns an iterator visiting all value names in order.

Source

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

Returns true if the section contains the provided value name.

Source

pub fn num_values(&self) -> usize

Returns the number of values in the section.

Source

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.
