Struct stack_graphs::c::sg_partial_scope_stack

#[repr(C)]
pub struct sg_partial_scope_stack {
    pub cells: sg_partial_scope_stack_cell_handle,
    pub direction: sg_deque_direction,
    pub length: u32,
    pub variable: sg_scope_stack_variable,
}

A pattern that might match against a scope stack. Consists of a (possibly empty) list of exported scopes, along with an optional scope stack variable.

Fields

cells: sg_partial_scope_stack_cell_handle

The handle of the first element in the partial scope stack, or SG_LIST_EMPTY_HANDLE if the list is empty, or 0 if the list is null.

direction: sg_deque_direction

length: u32

variable: sg_scope_stack_variable

The scope stack variable representing the unknown content of a partial scope stack, or 0 if the variable is missing. (If so, this partial scope stack can only match a scope stack with exactly the list of scopes in cells, instead of any scope stack with those scopes as a prefix.)

Trait Implementations

impl Clone for sg_partial_scope_stack

fn clone(&self) -> sg_partial_scope_stack

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for sg_partial_scope_stack

fn default() -> sg_partial_scope_stack

Returns the “default value” for a type.

impl From<PartialScopeStack> for sg_partial_scope_stack

fn from(stack: PartialScopeStack) -> sg_partial_scope_stack

Performs the conversion.

impl PartialEq<sg_partial_scope_stack> for sg_partial_scope_stack

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

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

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

This method tests for !=.
