This is used to increase the position when adding an appendix section to the pxar stream, as these bytes are never encoded directly but rather referenced by already existing chunks. Signed-off-by: Christian Ebner --- Changes since v2: - no changes Changes since v1: - add unsafe function signature in order to make it clear that calling `position_add` with incorrect size values will break the pxar archive encoding. src/encoder/aio.rs | 5 +++++ src/encoder/mod.rs | 6 ++++++ src/encoder/sync.rs | 5 +++++ 3 files changed, 16 insertions(+) diff --git a/src/encoder/aio.rs b/src/encoder/aio.rs index 5c7c7b9..8ff1364 100644 --- a/src/encoder/aio.rs +++ b/src/encoder/aio.rs @@ -112,6 +112,11 @@ impl<'a, T: SeqWrite + 'a> Encoder<'a, T> { self.inner.finish().await } + /// Add size to encoders position and return new position. + pub unsafe fn position_add(&mut self, size: u64) -> u64 { + unsafe { self.inner.position_add(size) } + } + /// Add reference to archive appendix pub async fn add_appendix_ref>( &mut self, diff --git a/src/encoder/mod.rs b/src/encoder/mod.rs index 3270d52..de23728 100644 --- a/src/encoder/mod.rs +++ b/src/encoder/mod.rs @@ -673,6 +673,12 @@ impl<'a, T: SeqWrite + 'a> EncoderImpl<'a, T> { self.state.write_position } + #[inline] + pub unsafe fn position_add(&mut self, size: u64) -> u64 { + self.state.write_position += size; + self.state.write_position + } + pub async fn create_directory( &mut self, file_name: &Path, diff --git a/src/encoder/sync.rs b/src/encoder/sync.rs index 2aaa6f2..a7f6b20 100644 --- a/src/encoder/sync.rs +++ b/src/encoder/sync.rs @@ -110,6 +110,11 @@ impl<'a, T: SeqWrite + 'a> Encoder<'a, T> { poll_result_once(self.inner.finish()) } + /// Add size to encoders position and return new position. + pub unsafe fn position_add(&mut self, size: u64) -> u64 { + unsafe { self.inner.position_add(size) } + } + /// Add reference to archive appendix pub async fn add_appendix_ref>( &mut self, -- 2.39.2
