pub struct ConditionId {
private_use_as_methods_instead: u32,
}
Expand description
ID of a mcdc condition. Used by llvm to check mcdc coverage.
Note for future: the max limit of 0xFFFF is probably too loose. Actually llvm does not
support decisions with too many conditions (7 and more at LLVM 18 while may be hundreds at 19)
and represents it with int16_t
. This max value may be changed once we could
figure out an accurate limit.

Implementations§
Source§impl ConditionId
impl ConditionId
Sourcepub const MAX_AS_U32: u32 = 65_535u32
pub const MAX_AS_U32: u32 = 65_535u32
Maximum value the index can take, as a u32
.
Sourcepub const fn from_usize(value: usize) -> Self
pub const fn from_usize(value: usize) -> Self
Sourcepub const unsafe fn from_u32_unchecked(value: u32) -> Self
pub const unsafe fn from_u32_unchecked(value: u32) -> Self
Creates a new index from a given u32
.
§Safety
The provided value must be less than or equal to the maximum value for the newtype. Providing a value outside this range is undefined due to layout restrictions.
Prefer using from_u32
.
