Struct icu::compactdecimal::provider::Pattern

pub struct Pattern<'data> {
    pub exponent: i8,
    pub index: u8,
    pub literal_text: Cow<'data, str>,
}

A compact decimal pattern, representing some literal text with an optional placeholder, and the power of 10 expressed by the text.

Fields

exponent: i8

The compact decimal exponent, e.g., 6 for “million”. The value 0 indicates that compact notation is not used; in that case, literal text must be empty; this corresponds to the CLDR pattern “0”. This is derived from the numbers of 0s in the pattern and the associated type attribute; it is a more convenient representation than the number of 0s, because it is often common to multiple types; for instance, the following correspond to the same Pattern: 0 M 00 M

index: u8

The index in literal_text before which the placeholder is inserted; this is 0 for insertion at the beginning, which is most common. The value 255 indicates that the pattern does not have a placeholder, as in French “mille” for 1000.

literal_text: Cow<'data, str>

The underlying CLDR pattern with the placeholder removed, e.g., “ M“ for the pattern “000 M”

Trait Implementations

impl<'data> Clone for Pattern<'data>

fn clone(&self) -> Pattern<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for Pattern<'data>

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

Formats the value using the given formatter.

impl<'data> Default for Pattern<'data>

fn default() -> Pattern<'data>

Returns the “default value” for a type.

impl<'data> EncodeAsVarULE<PatternULE> for &Pattern<'data>

fn encode_var_ule_as_slices<R>(&self, cb: impl FnOnce(&[&[u8]]) -> R) -> R

Calls cb with a piecewise list of byte slices that when concatenated produce the memory pattern of the corresponding instance of T.

fn encode_var_ule_len(&self) -> usize

Return the length, in bytes, of the corresponding [VarULE] type

fn encode_var_ule_write(&self, dst: &mut [u8])

Write the corresponding [VarULE] type to the dst buffer. dst should be the size of [Self::encode_var_ule_len()]

Return the length, in bytes, of the corresponding [VarULE] type

fn encode_var_ule_write(&self, dst: &mut [u8])

Write the corresponding [VarULE] type to the dst buffer. dst should be the size of [Self::encode_var_ule_len()]

impl<'data> Ord for Pattern<'data>

fn cmp(&self, other: &Pattern<'data>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<'data> PartialEq<Pattern<'data>> for Pattern<'data>

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

fn partial_cmp(&self, other: &Pattern<'data>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<'a> Yokeable<'a> for Pattern<'static>

type Output = Pattern<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a <Pattern<'static> as Yokeable<'a>>::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> <Pattern<'static> as Yokeable<'a>>::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make( this: <Pattern<'static> as Yokeable<'a>>::Output ) -> Pattern<'static>

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)where F: 'static + for<'b> FnOnce(&'b mut <Pattern<'static> as Yokeable<'a>>::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

fn zero_from(other: &'data PatternULE) -> Pattern<'data>

Clone the other C into a struct that may retain references into C.
