Struct subtle::Choice
[−]
[src]
pub struct Choice(_);
The Choice struct represents a choice for use in conditional
assignment.
It is a wrapper around a u8, which should have the value either
1 (true) or 0 (false).
With the nightly feature enabled, the conversion from u8 to
Choice passes the value through an optimization barrier, as a
best-effort attempt to prevent the compiler from inferring that the
Choice value is a boolean.
