Struct Lifetime

pub struct Lifetime {
    pub apostrophe: Span,
    pub ident: Ident,
}

A Rust lifetime: 'a.

Lifetime names must conform to the following rules:

• Must start with an apostrophe.
• Must not consist of just an apostrophe: '.
• Character after the apostrophe must be _ or a Unicode code point with the XID_Start property.
• All following characters must be Unicode code points with the XID_Continue property.

Fields

apostrophe: Span

ident: Ident

Implementations

impl Lifetime

pub fn new(symbol: &str, span: Span) -> Self

Panics

Panics if the lifetime does not conform to the bulleted rules above.

Invocation

Lifetime::new("'a", Span::call_site())

pub fn span(&self) -> Span

pub fn set_span(&mut self, span: Span)

Trait Implementations

impl Clone for Lifetime

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lifetime

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl Display for Lifetime

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

Formats the value using the given formatter.

impl From<Lifetime> for TypeParamBound

fn from(e: Lifetime) -> TypeParamBound

Converts to this type from the input type.

impl Hash for Lifetime

fn hash<H: Hasher>(&self, h: &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 Ord for Lifetime

fn cmp(&self, other: &Lifetime) -> 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 Parse for Lifetime

Available on crate feature parsing only.

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for Lifetime

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

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

impl ToTokens for Lifetime

Available on crate feature printing only.

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for Lifetime

impl Token for Lifetime

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
