Struct Parser 

pub struct Parser<'pat> {
    pub pattern: &'pat str,
    pub file_id: usize,
    pub ecma_version: EcmaVersion,
    /* private fields */
}

The actual parser that is responsible for parsing regex.

Fields

pattern: &'pat str

file_id: usize

ecma_version: EcmaVersion

Implementations

impl<'pat> Parser<'pat>

pub fn new( pattern: &'pat str, file_id: usize, offset: usize, ecma_version: EcmaVersion, strict: bool, ) -> Result<Self>

Creates a new Parser from a given full pattern.

The given offset is used to convert the relative position in the pattern into an absolute position inside a file. The pattern must be the pattern without the leading and trailing /

Panics

Panics if there is no leading or trailing /

Returns

Returns a Result from parsing flags

pub fn new_from_pattern_and_flags( pattern: &'pat str, file_id: usize, offset: usize, ecma_version: EcmaVersion, strict: bool, flags: Flags, ) -> Self

impl Parser<'_>

pub fn parse(self) -> Result<Regex>

The main entrypoint for parsing a RegEx pattern.
