Struct GpkgBinaryParser 

pub struct GpkgBinaryParser;

Parser and encoder for the GeoPackageBinary (GPB) and WKB geometry formats.

The GeoPackageBinary layout is:

magic[2]     = 0x47 0x50  ("GP")
version[1]
flags[1]     bits 0-2: envelope indicator
             bit  3:   empty-geometry flag
             bit  5:   byte order (0=BE, 1=LE)
srs_id[4]    i32, same byte order as flags bit 5
envelope     0/32/48/64 bytes depending on flags bits 0-2
WKB          remainder of the blob

Implementations

impl GpkgBinaryParser

pub fn parse(data: &[u8]) -> Result<GpkgGeometry, GpkgError>

Parse a GeoPackageBinary blob into a GpkgGeometry.

Errors

• GpkgError::InvalidGeometryMagic — first two bytes are not GP
• GpkgError::InsufficientData — blob too short
• GpkgError::WkbParseError / GpkgError::UnknownWkbType — WKB invalid

pub fn parse_wkb(data: &[u8]) -> Result<GpkgGeometry, GpkgError>

Parse a WKB (Well-Known Binary) blob into a GpkgGeometry.

Both big-endian (byte_order = 0) and little-endian (byte_order = 1) WKB are supported.

pub fn to_wkb(geom: &GpkgGeometry) -> Vec<u8>

Encode a GpkgGeometry as little-endian WKB.

pub fn to_gpb(geom: &GpkgGeometry, srs_id: i32) -> Vec<u8>

Encode a GpkgGeometry as a GeoPackageBinary blob (no envelope, LE byte order).

The resulting bytes begin with the magic GP (0x47 0x50).
