Struct ModuleKey 

pub struct ModuleKey(/* private fields */);

The key of one parse result: a 128-bit SipHash-1-3 of the schema, the crate version, the parser, the parse options, the file name and the text. The directory is not part of it, so identical files share an entry and a moved checkout keeps its cache.

Implementations

impl ModuleKey

pub fn new(path: &Path, source: &str, options: &ParseOptions) -> Self

The key for parsing source, the text of path, with options.

pub const fn to_bytes(self) -> [u8; 16]

The key as 16 little-endian bytes, for a host that persists it.

pub const fn from_bytes(bytes: [u8; 16]) -> Self

A key from the bytes ModuleKey::to_bytes gave.
