Trait scroll::TryOffsetWith

pub trait TryOffsetWith<Ctx = DefaultCtx, E = Error, I = usize> {
    fn try_offset<N: SizeWith<Ctx, Units = I>>(
        &self, 
        offset: I, 
        ctx: &Ctx
    ) -> 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: SizeWith<Ctx, Units = I>>(
    &self,
    offset: I,
    ctx: &Ctx
) -> Result<I, E>

Given the offset, see if a size + offset can safely be performed on Self, and return the resulting computed size
