Struct geozero::mvt::tile::Layer

pub struct Layer {
    pub version: u32,
    pub name: String,
    pub features: Vec<Feature>,
    pub keys: Vec<String>,
    pub values: Vec<Value>,
    pub extent: Option<u32>,

Layers are described in section 4.1 of the specification

Fields

version: u32

Any compliant implementation must first read the version number encoded in this message and choose the correct implementation for this version number before proceeding to decode other parts of this message.

name: String

features: Vec<Feature>

The actual features in this tile.

keys: Vec<String>

Dictionary encoding for keys

values: Vec<Value>

Dictionary encoding for values

extent: Option<u32>

Although this is an “optional” field it is required by the specification. See https://github.com/mapbox/vector-tile-spec/issues/47

Implementations

impl Layer

pub fn extent(&self) -> u32

Returns the value of extent, or the default value if extent is unset.

Trait Implementations

impl Clone for Layer

fn clone(&self) -> Layer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Layer

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

Formats the value using the given formatter.

impl Default for Layer

fn default() -> Self

Returns the “default value” for a type.

impl GeozeroDatasource for Layer

fn process<P: FeatureProcessor>(&mut self, processor: &mut P) -> Result<()>

Consume and process all selected features.

fn process_geom<P: GeomProcessor>(&mut self, processor: &mut P) -> Result<()>

Consume and process geometries of all selected features.

impl Message for Layer

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Layer

fn eq(&self, other: &Layer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
