Struct Span 

pub struct Span { /* private fields */ }

A duration as this crate’s documents spell one: one or more digits, then exactly one unit letter — 7d, 36h, 90m, 600s.

One grammar rather than a free one, and deliberately narrow: no spaces, no combination (1h30m), no fraction, no sign, and no zero, because every place a span is written names a wait or a bound and a bound of nothing is a mistake rather than a choice. The check is in the conversion, so a document naming a span this grammar refuses does not deserialize at all. It is exported because a consumer parses its own schedule through it, so the two cannot come to read one spelling two ways.

Implementations

impl Span

pub fn as_duration(&self) -> Duration

The duration this span names.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Span

impl Debug for Span

The span itself, quoted — never the wrapper, for the reason every other document value in this crate spells its own Debug that way.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Span

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Span

As written: the number and its unit letter, so a document round-trips byte for byte.

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

Formats the value using the given formatter.

impl Eq for Span

impl FromStr for Span

type Err = String

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<Self, Self::Err>

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

impl Hash for Span

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

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 PartialEq for Span

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Span

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
