Enum rustc_borrowck::LocalMutationIsAllowed

source · [−]

pub(crate) enum LocalMutationIsAllowed {
    Yes,
    ExceptUpvars,
    No,
}

Expand description

When checking permissions for a place access, this flag is used to indicate that an immutable local place can be mutated.

Variants

`Yes`

`ExceptUpvars`

We want use of immutable upvars to cause a “write to immutable upvar” error, not an “reassignment” error.

`No`

Trait Implementations

source

impl Clone for LocalMutationIsAllowed

source

fn clone(&self) -> LocalMutationIsAllowed

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for LocalMutationIsAllowed

source

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

Formats the value using the given formatter. Read more

source

impl PartialEq<LocalMutationIsAllowed> for LocalMutationIsAllowed

source

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

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

1.0.0 · source

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
