Enum Segment

pub enum Segment<'a> {
    Number(Number<'a>),
    Text(Text<'a>),
}

A reference to a homogenous segment of text in a string.

Ord and Eq are implemented for this type, which delegate to their respective types for same variant comparison, and otherwise considers every Segment::Number to come before every Segment::Text.

Variants

Number(Number<'a>)

Text(Text<'a>)

Implementations

impl<'a> Segment<'a>

pub fn read(src: &'a str, force_text: bool) -> Option<Self>

Greedily reads a (non-empty) Text or Number segment from the beginning of the string. Number values are preferred over text values, but can be disabled (entirely) by setting force_text to true. Returns None if a segment cannot be extracted.

pub fn as_str(&self) -> &'a str

Returns the (non-empty) substring that was read via Segment::read.

pub fn as_number(&self) -> Option<Number<'a>>

Retrieves the value of the Segment::Number variant, or None if that is not the current variant.

pub fn as_text(&self) -> Option<Text<'a>>

Retrieves the value of the Segment::Text variant, or None if that is not the current variant.

Trait Implementations

impl<'a> Clone for Segment<'a>

fn clone(&self) -> Segment<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Segment<'a>

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

Formats the value using the given formatter.

impl<'a> Ord for Segment<'a>

fn cmp(&self, other: &Segment<'a>) -> 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<'a> PartialEq for Segment<'a>

fn eq(&self, other: &Segment<'a>) -> 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<'a> PartialOrd for Segment<'a>

fn partial_cmp(&self, other: &Segment<'a>) -> 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.
