pub enum ScopeData {
    Node,
    CallSite,
    Arguments,

}

Variants

Node

CallSite

Scope of the call-site for a function or closure (outlives the arguments as well as the body).

Arguments

Scope of arguments passed to a function or closure (they outlive its body).

Destruction

Scope of destructors for temporaries of node-id.

Remainder

Scope following a let id = expr; binding in a block.

Tuple Fields of Remainder

0: FirstStatementIndex

    __hasher: &mut StableHasher
)

impl Ord for ScopeData

fn cmp(&self, other: &ScopeData) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<ScopeData> for ScopeData

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<ScopeData> for ScopeData

fn partial_cmp(&self, other: &ScopeData) -> 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

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
