Struct HostLogger 

pub struct HostLogger;

Logger implementation that forwards records to the host.

This integrates the Rust log crate with the http-wasm guest runtime’s logging system. It provides logging for plugin authors via standard macros (log::info!, log::warn!, etc.).

Implementations

impl HostLogger

pub fn init() -> Result<(), SetLoggerError>

Initialize the host-backed logger with the default Info level.

This is a convenience function for [init_with_level] using Level::Info.

Examples found in repository

examples/info.rs (line 33)

fn main() {
    let _ = HostLogger::init();
    admin::enable(feature::BufferRequest | feature::BufferResponse);
    let plugin = Plugin {};
    register(plugin);
}

pub fn init_with_level(level: Level) -> Result<(), SetLoggerError>

Initialize the host-backed logger with a specific maximum level.

This registers a HostLogger implementation for forwarding log records to the http-wasm host.
