Struct MemoryResolver

pub struct MemoryResolver { /* private fields */ }

Serves layers held in memory, keyed by the exact import uri, like upstream’s InMemoryLayerProvider.

Implementations

impl MemoryResolver

pub fn new() -> Self

pub fn insert( &mut self, uri: impl Into<String>, bytes: impl Into<Vec<u8>>, ) -> Option<Vec<u8>>

Serves bytes for uri, replacing and returning any earlier entry.

pub fn insert_file( &mut self, file: &IfcxFile, ) -> Result<Option<Vec<u8>>, WriteError>

Serves file under its header.id, as upstream’s in-memory provider does. An integrity check on such a layer hashes the JSON this crate writes, not any original bytes.

Trait Implementations

impl Clone for MemoryResolver

fn clone(&self) -> MemoryResolver

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryResolver

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

Formats the value using the given formatter.

impl Default for MemoryResolver

fn default() -> MemoryResolver

Returns the “default value” for a type.

impl LayerResolver for MemoryResolver

type Error = Infallible

Failure other than a missing layer, such as an I/O error.

fn load(&mut self, key: &str) -> Result<Option<Vec<u8>>, Self::Error>

Returns the bytes of the layer with this key, or Ok(None) when there is no such layer.

fn key( &mut self, uri: &str, importer: Option<&str>, ) -> Result<String, Self::Error>

Identifies the layer that uri names. importer is the key of the layer whose imports list uri, or None for the main layer, so relative references can resolve against it.
