Struct cursive_core::view::SizeCache
source · Expand description
Cache around a one-dimensional layout result.
This is not a View, but something to help you if you create your own Views.
Fields§
§value: usize
Cached value
constrained: bool
true
if the last size was constrained.
If unconstrained, any request larger than this value would return the same size.
extra: T
Extra field.
Implementations§
source§impl SizeCache<()>
impl SizeCache<()>
sourcepub fn build(size: Vec2, req: Vec2) -> XY<Self>
pub fn build(size: Vec2, req: Vec2) -> XY<Self>
Creates a new bi-dimensional cache.
It will stay valid for the same request, and compatible ones.
A compatible request is one where, for each axis, either:
- the request is equal to the cached size, or
- the request is larger than the cached size and the cache is unconstrained
Notes:
size
must fit insidereq
.- for each dimension,
constrained = (size == req)
