Delegate HttpHeaderTransformCallback

Namespace

Maplibre.NativeFfi

Assembly

Maplibre.NativeFfi.dll

Sets the headers of an HTTP request before the library sends it.

public delegate void HttpHeaderTransformCallback(ResourceKind kind, string url, HttpHeaderTransformResponse outResponse)

Parameters

kind ResourceKind

Sets the headers of an HTTP request before the library sends it.

url string

Sets the headers of an HTTP request before the library sends it.

outResponse HttpHeaderTransformResponse

Sets the headers of an HTTP request before the library sends it.

Remarks

url is the request's URL after any resource transform. The request waits for the callback, so return quickly.

Runs on a library thread.

Returning succeeds. Throwing a MaplibreException whose status is not Status.Ok fails the call with that status. Any other exception fails it with Status.NativeError and is reported to MaplibreNative.CallbackException.
