Struct Pattern 

pub struct Pattern {
    pub source: String,
    pub dialect: Dialect,
    pub flags: Flags,
    pub ast: Node,
    pub group_count: u32,
    pub group_names: Vec<String>,
    pub notes: Vec<String>,
}

A parsed pattern.

Fields

source: String

Original text.

dialect: Dialect

Dialect it was written for.

flags: Flags

Effective global flags (option flags plus leading inline flags).

ast: Node

Syntax tree.

group_count: u32

Number of capturing groups.

group_names: Vec<String>

Names of named groups, in order of appearance.

notes: Vec<String>

Non-fatal notes (for example ignored flags).

Implementations

impl Pattern

pub fn parse( source: &str, dialect: Dialect, flags: Flags, ) -> Result<Pattern, RexactError>

Parse with default limits.

pub fn parse_with( source: &str, dialect: Dialect, flags: Flags, limits: &ParseLimits, ) -> Result<Pattern, RexactError>

Parse with explicit limits.

pub fn parse_literal( text: &str, dialect: Dialect, ) -> Result<Pattern, RexactError>

Parse a /body/flags literal (FR-A03). Flag letters are interpreted for dialect; letters that do not change the language become notes.

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.
