Struct debian_packaging::io::PathMappingDataResolver

pub struct PathMappingDataResolver<R> { /* fields omitted */ }

A DataResolver that maintains a path translation table and transparently redirects lookups.

Implementations

impl<R: DataResolver + Send> PathMappingDataResolver<R>

pub fn new(source: R) -> Self

Construct a new instance that forwards to a source DataResolver.

pub fn add_path_map(&mut self, from_path: impl ToString, to_path: impl ToString)

Register a mapping of 1 path to another.

Future looks up from_path will resolve to to_path.

Trait Implementations

fn get_path<'life0, 'life1, 'async_trait>(
    &'life0 self,
    path: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn AsyncRead + Send>>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Get the content of a relative path as an async reader.

fn get_path_with_digest_verification<'life0, 'life1, 'async_trait>(
    &'life0 self,
    path: &'life1 str,
    expected_size: u64,
    expected_digest: ContentDigest
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn AsyncRead + Send>>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Obtain a reader that performs content integrity checking.

fn get_path_decoded<'life0, 'life1, 'async_trait>(
    &'life0 self,
    path: &'life1 str,
    compression: Compression
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn AsyncRead + Send>>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Get the content of a relative path with decompression transparently applied.

fn get_path_decoded_with_digest_verification<'life0, 'life1, 'async_trait>(
    &'life0 self,
    path: &'life1 str,
    compression: Compression,
    expected_size: u64,
    expected_digest: ContentDigest
) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn AsyncRead + Send>>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Like Self::get_path_decoded() but also perform content integrity verification.
