Struct InitialRead 

pub struct InitialRead {
    pub buf: Bytes,
    pub initial_read_offset: u64,
    pub fb_postscript_byte_range: Range<usize>,
}

Fields

buf: Bytes

The bytes from the initial read of the file, which is assumed (for now) to be sufficiently large to contain the schema and layout.

initial_read_offset: u64

The absolute byte offset representing the start of the initial read within the file.

fb_postscript_byte_range: Range<usize>

The byte range within buf representing the Postscript flatbuffer.

Implementations

impl InitialRead

pub fn fb_postscript(&self) -> VortexResult<Postscript<'_>>

pub fn fb_layout_byte_range(&self) -> VortexResult<Range<usize>>

The bytes of the Layout flatbuffer.

pub fn fb_layout(&self) -> VortexResult<Layout<'_>>

The Layout flatbuffer.

pub fn fb_schema_byte_range(&self) -> VortexResult<Range<usize>>

The bytes of the Schema flatbuffer.

pub fn fb_schema(&self) -> VortexResult<Schema<'_>>

The Schema flatbuffer.

pub fn lazy_dtype(&self) -> VortexResult<LazilyDeserializedDType>

Trait Implementations
