Struct PooledTileSource 

pub struct PooledTileSource { /* private fields */ }

A TileSource that fetches tiles over HTTP with concurrency limiting and viewport-center priority ordering via FetchPool.

Implementations

impl PooledTileSource

pub fn new( url_template: impl Into<String>, client: Box<dyn HttpClient>, max_concurrent: usize, ) -> Self

Create a new pooled tile source without image decoding.

Response bodies are assumed to be raw RGBA8 256x256 pixel data. For real tile providers use with_decoder.

pub fn with_decoder( url_template: impl Into<String>, client: Box<dyn HttpClient>, max_concurrent: usize, decoder: Box<dyn TileDecoder>, ) -> Self

Create a new pooled tile source with a TileDecoder.

pub fn with_header( self, name: impl Into<String>, value: impl Into<String>, ) -> Self

Add a default header that will be sent with every tile request.

Trait Implementations
