Struct rustc_data_structures::stable_hasher::StableHasher
[−]
[src]
pub struct StableHasher<W> { /* fields omitted */ }
When hashing something that ends up affecting properties like symbol names, we want these symbol names to be calculated independently of other factors like what architecture you're compiling from.
To that end we always convert integers to little-endian format before
hashing and the architecture dependent isize
and usize
types are
extended to 64 bits if needed.
