Struct osmpbf::blob::Blob

pub struct Blob { /* fields omitted */ }

A blob.

A PBF file consists of a sequence of blobs. This type supports decoding the content of a blob to different types of blocks that are usually more interesting to the user.

Implementations

impl Blob

pub fn decode(&self) -> Result<BlobDecode<'_>>

Decodes the Blob and tries to obtain the inner content (usually a HeaderBlock or a PrimitiveBlock). This operation might involve an expensive decompression step.

pub fn get_type(&self) -> BlobType<'_>

Returns the type of a blob without decoding its content.

pub fn offset(&self) -> Option<ByteOffset>

Returns the byte offset of the blob from the start of its source stream. This might be None if the source stream does not implement Seek.

pub fn to_headerblock(&self) -> Result<HeaderBlock>

Tries to decode the blob to a HeaderBlock. This operation might involve an expensive decompression step.

pub fn to_primitiveblock(&self) -> Result<PrimitiveBlock>

Tries to decode the blob to a PrimitiveBlock. This operation might involve an expensive decompression step.

Trait Implementations

impl Clone for Blob

fn clone(&self) -> Blob

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blob

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

Formats the value using the given formatter.
