Struct hyperscan::ExprExt

#[repr(transparent)]
pub struct ExprExt(_);

A structure containing additional parameters related to an expression.

Implementations

impl ExprExt

pub fn is_empty(&self) -> bool

Returns true if the expression contains no additional parameters.

pub fn min_offset(&self) -> Option<u64>

The minimum end offset in the data stream at which this expression should match successfully.

pub fn max_offset(&self) -> Option<u64>

The maximum end offset in the data stream at which this expression should match successfully.

pub fn min_length(&self) -> Option<u64>

The minimum match length (from start to end) required to successfully match this expression.

pub fn edit_distance(&self) -> Option<u32>

Allow patterns to approximately match within this edit distance.

pub fn hamming_distance(&self) -> Option<u32>

Allow patterns to approximately match within this Hamming distance.

pub fn set_min_offset(&mut self, min_offset: u64) -> &mut Self

Sets the value for the minimum end offset in the data stream at which this expression should match successfully.

pub fn set_max_offset(&mut self, max_offset: u64) -> &mut Self

Sets the value for the maximum end offset in the data stream at which this expression should match successfully.

pub fn set_min_length(&mut self, min_length: u64) -> &mut Self

Sets the value for the minimum match length (from start to end) required to successfully match this expression.

pub fn set_edit_distance(&mut self, edit_distance: u32) -> &mut Self

Sets the value that allow patterns to approximately match within this edit distance.

pub fn set_hamming_distance(&mut self, hamming_distance: u32) -> &mut Self

Sets the value that allow patterns to approximately match within this Hamming distance.

Trait Implementations

impl Clone for ExprExt

fn clone(&self) -> ExprExt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprExt

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

Formats the value using the given formatter.

impl Default for ExprExt

fn default() -> ExprExt

Returns the “default value” for a type.

impl Display for ExprExt

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

Formats the value using the given formatter.

impl From<ExprExt> for hs_expr_ext_t

fn from(original: ExprExt) -> Self

Converts to this type from the input type.

impl From<hs_expr_ext> for ExprExt

fn from(original: hs_expr_ext_t) -> ExprExt

Converts to this type from the input type.

impl FromStr for ExprExt

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

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

impl PartialEq<ExprExt> for ExprExt

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