Implementations

impl RevisionSuffix

pub const fn parent_number( number: u32, ) -> Result<RevisionSuffix, RevisionParseError>

Creates a numbered parent suffix.

Errors

Returns RevisionParseError::ZeroSuffixCount when number is zero.

pub const fn ancestor(count: u32) -> Result<RevisionSuffix, RevisionParseError>

Creates an ancestor suffix.

Errors

Returns RevisionParseError::ZeroSuffixCount when count is zero.

Trait Implementations

impl Clone for RevisionSuffix

fn clone(&self) -> RevisionSuffix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RevisionSuffix

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

Formats the value using the given formatter.

impl Display for RevisionSuffix

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

Formats the value using the given formatter.

impl Hash for RevisionSuffix

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RevisionSuffix

fn cmp(&self, other: &RevisionSuffix) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RevisionSuffix

fn eq(&self, other: &RevisionSuffix) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RevisionSuffix

fn partial_cmp(&self, other: &RevisionSuffix) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
