Enum ThreadIdLabel 

pub enum ThreadIdLabel {
    Label(String),
    Number(u64),
}

A stable label or numeric thread-like identifier.

Variants

Label(String)

A caller-provided stable thread label.

Number(u64)

A caller-provided numeric thread-like identifier.

Implementations

impl ThreadIdLabel

pub fn label( value: impl AsRef<str>, ) -> Result<ThreadIdLabel, ThreadIdLabelError>

Creates a thread ID label from non-empty text.

Errors

Returns ThreadIdLabelError::Empty when the trimmed input is empty.

pub const fn number(value: u64) -> ThreadIdLabel

Creates a numeric thread-like identifier.

pub fn as_label(&self) -> Option<&str>

Returns the label text when this value is label-backed.

pub const fn as_number(&self) -> Option<u64>

Returns the numeric identifier when this value is number-backed.

Trait Implementations

impl Clone for ThreadIdLabel

fn clone(&self) -> ThreadIdLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadIdLabel

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

Formats the value using the given formatter.

impl Display for ThreadIdLabel

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

Formats the value using the given formatter.

impl FromStr for ThreadIdLabel

type Err = ThreadIdLabelError

The associated error which can be returned from parsing.

fn from_str( value: &str, ) -> Result<ThreadIdLabel, <ThreadIdLabel as FromStr>::Err>

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

impl Hash for ThreadIdLabel

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 ThreadIdLabel

fn cmp(&self, other: &ThreadIdLabel) -> 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 ThreadIdLabel

fn eq(&self, other: &ThreadIdLabel) -> 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 ThreadIdLabel

fn partial_cmp(&self, other: &ThreadIdLabel) -> 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.
