Struct debian_packaging::io::PathMappingDataResolver

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

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

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

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: '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 Self: 'async_trait, 'life0: 'async_trait, 'life1: '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 Self: 'async_trait, 'life0: 'async_trait, 'life1: '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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

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