Enum FetchHashMode 

pub enum FetchHashMode {
    Flat,
    Recursive,
    Sri,
}

How the fetcher computes the result’s content hash.

Variants

Flat

Hash the bytes directly. Used for single files (e.g. a tarball downloaded by fetchurl with unpack = false).

Recursive

NAR-hash the unpacked tree. Used for fetchTarball with unpack = true, fetchGit, fetchTree, and builtins.path on directories.

Sri

SRI hash format passthrough (sha256-base64=). Modern surface; supersedes Flat/Recursive for many call sites.

Trait Implementations

impl Clone for FetchHashMode

fn clone(&self) -> FetchHashMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FetchHashMode

impl Debug for FetchHashMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FetchHashMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FetchHashMode

impl PartialEq for FetchHashMode

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FetchHashMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
