Struct hyperscan::chimera::prelude::Pattern

pub struct Pattern {
    pub expression: String,
    pub flags: Flags,
    pub id: Option<usize>,
}

The pattern with basic regular expression.

Fields

expression: String

The expression to parse.

flags: Flags

Flags which modify the behaviour of the expression.

id: Option<usize>

ID number to be associated with the corresponding pattern in the expressions array.

Implementations

impl Pattern

pub fn new<S: Into<String>>(expr: S) -> Pattern

Construct a pattern with expression.

pub fn with_flags<S: Into<String>>(expr: S, flags: Flags) -> Pattern

Construct a pattern with expression and flags.

pub fn caseless(self) -> Self

Set case-insensitive matching.

pub fn dot_all(self) -> Self

Matching a . will not exclude newlines.

pub fn multi_line(self) -> Self

Set multi-line anchoring.

pub fn single_match(self) -> Self

Set single-match only mode.

pub fn utf8(self) -> Self

Enable UTF-8 mode for this expression.

pub fn ucp(self) -> Self

Enable Unicode property support for this expression.

Trait Implementations

impl Builder for Pattern

fn for_platform(
    &self,
    mode: Mode,
    match_limit: Option<MatchLimit>,
    platform: Option<&PlatformRef>
) -> Result<Database, Self::Err>

The basic regular expression compiler.

This is the function call with which an expression is compiled into a Chimera database which can be passed to the runtime function.

type Err = Error

The associated error which can be returned from compiling.

fn build(&self) -> Result<Database, Self::Err>

Build an expression is compiled into a Chimera database which can be passed to the runtime functions.

fn with_groups(&self) -> Result<Database, Self::Err>

Build an expression is compiled into a Chimera database that the database as a whole for capturing groups.

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a copy 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.

impl Display for Pattern

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

Formats the value using the given formatter.

impl FromIterator<Pattern> for Patterns

fn from_iter<T: IntoIterator<Item = Pattern>>(iter: T) -> Self

Creates a value from an iterator.

impl FromStr for Pattern

type Err = Error

The associated error which can be returned from parsing.

fn from_str(expr: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<Pattern> for Pattern

fn eq(&self, other: &Pattern) -> 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.

impl Eq for Pattern

impl StructuralEq for Pattern

impl StructuralPartialEq for Pattern
