Enum rustc_query_system::dep_graph::FingerprintStyle

source · [−]

pub enum FingerprintStyle {
    DefPathHash,
    HirId,
    Unit,
    Opaque,
}

Expand description

Describes the contents of the fingerprint generated by a given query.

Variants

`DefPathHash`

The fingerprint is actually a DefPathHash.

`HirId`

The fingerprint is actually a HirId.

`Unit`

Query key was () or equivalent, so fingerprint is just zero.

`Opaque`

Some opaque hash.

impl Clone for FingerprintStyle

source

fn clone(&self) -> FingerprintStyle

Returns a copy of the value. Read more

source

impl PartialEq<FingerprintStyle> for FingerprintStyle

source

fn eq(&self, other: &FingerprintStyle) -> bool

This method tests for self and other values to be equal, and is used by ==. Read more

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
