Implementations

impl<O> AssertKind<O>

pub fn description(&self) -> &'static str

Getting a description does not require O to be printable, and does not require allocation. The caller is expected to handle BoundsCheck separately.

pub fn fmt_assert_args<W: Write>(&self, f: &mut W) -> Result where
    O: Debug, 

Format the message arguments for the assert(cond, msg..) terminator in MIR printing.

Trait Implementations

impl<O: Clone> Clone for AssertKind<O>

fn clone(&self) -> AssertKind<O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<O: Debug> Debug for AssertKind<O>

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