Trait scroll::TryOffset
[−]
[src]
pub trait TryOffset<E = Error, I = usize> { fn try_offset<N>(&self, offset: I) -> Result<I, E>; }
Attempt to add an offset for a given N's size, used to compute error values in Gread, or return the N's size in units the same as the offset
NB: this trait's name is likely to be changed, tweaked slightly, if you are implementing an entire Pread stack, beware this could change
Required Methods
fn try_offset<N>(&self, offset: I) -> Result<I, E>
Given the offset, see if a size + offset can safely be performed on Self, and return the resulting computed size
