Enum regex_syntax::hir::Anchor

pub enum Anchor {
    StartLine,
    EndLine,
    StartText,
    EndText,
}

The high-level intermediate representation for an anchor assertion.

A matching anchor assertion is always zero-length.

Variants

StartLine

Match the beginning of a line or the beginning of text. Specifically, this matches at the starting position of the input, or at the position immediately following a \n character.

EndLine

Match the end of a line or the end of text. Specifically, this matches at the end position of the input, or at the position immediately preceding a \n character.

StartText

Match the beginning of text. Specifically, this matches at the starting position of the input.

EndText

Match the end of text. Specifically, this matches at the ending position of the input.

Trait Implementations

impl Clone for Anchor

fn clone(&self) -> Anchor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Anchor

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

Formats the value using the given formatter.

impl PartialEq<Anchor> for Anchor

fn eq(&self, other: &Anchor) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
