Enum TemplateIdentifier 

pub enum TemplateIdentifier<'a> {
    Implicit(usize),
    Positional(usize),
    Named(&'a str),
}

Placeholder identifier parsed from the template.

Variants

Implicit(usize)

Implicit positional index inferred from the placeholder order ({} / {:?} / etc.).

Positional(usize)

Positional index ({0} / {1:?} / etc.).

Named(&'a str)

Named field ({name} / {kind:?} / etc.).

Implementations

impl<'a> TemplateIdentifier<'a>

pub const fn as_str(&self) -> Option<&'a str>

Returns the identifier as a string when it is named.

Trait Implementations

impl<'a> Clone for TemplateIdentifier<'a>

fn clone(&self) -> TemplateIdentifier<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TemplateIdentifier<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TemplateIdentifier<'a>

fn eq(&self, other: &TemplateIdentifier<'a>) -> 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.
