Struct pipe_chain::pipe::Repetition

pub struct Repetition { /* private fields */ }

Represents a range or a fixed number

the upper limit is optionally defined

Implementations

impl Repetition

pub fn range(min: usize, max: Option<usize>) -> Result<Self, InvalidRepetition>

Creates a new repetition

max is inclusive

returns an error if min > max

pub fn exact(n: usize) -> Result<Self, InvalidRepetition>

Creates a new repetition with a fixed number

pub fn needs_more(&self, nb: usize) -> bool

Return true if nb < min

pub fn is_max(&self, nb: usize) -> bool

Return true if nb == max

pub fn map_err<E>( &self, nb: usize, f: impl FnOnce(usize, Option<usize>, usize) -> E ) -> Result<(), E>

Error handling

Calls the provided function f with min, max, nb if nb is outside of the repetition boundaries

pub fn min_needed(&self, nb: usize) -> usize

Returns the minimum number of repetitions needed after nb repetitions

Trait Implementations

impl Clone for Repetition

fn clone(&self) -> Repetition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Repetition

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

Formats the value using the given formatter.

impl From<RangeFrom<usize>> for Repetition

fn from(value: RangeFrom<usize>) -> Self

Converts to this type from the input type.

impl From<RangeFull> for Repetition

fn from(_: RangeFull) -> Self

Converts to this type from the input type.

impl PartialEq for Repetition

fn eq(&self, other: &Repetition) -> 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 TryFrom<Range<usize>> for Repetition

type Error = InvalidRepetition

The type returned in the event of a conversion error.

fn try_from(value: Range<usize>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<RangeInclusive<usize>> for Repetition

type Error = InvalidRepetition

The type returned in the event of a conversion error.

fn try_from(value: RangeInclusive<usize>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<RangeTo<usize>> for Repetition

type Error = InvalidRepetition

The type returned in the event of a conversion error.

fn try_from(value: RangeTo<usize>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<RangeToInclusive<usize>> for Repetition

type Error = InvalidRepetition

The type returned in the event of a conversion error.

fn try_from(value: RangeToInclusive<usize>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<usize> for Repetition

type Error = InvalidRepetition

The type returned in the event of a conversion error.

fn try_from(value: usize) -> Result<Self, Self::Error>

Performs the conversion.
