Struct RequestLogger 

pub struct RequestLogger {
    pub log_bodies: bool,
    pub max_body_log_bytes: usize,
}

Middleware that logs each request and its corresponding response.

Emits structured log lines via tracing. Body logging is opt-in and truncated at max_body_log_bytes to avoid flooding logs with large payloads.

Fields

log_bodies: bool

Whether to include body content in log output.

max_body_log_bytes: usize

Maximum number of body bytes to include in a log line.

Implementations

impl RequestLogger

pub fn new() -> Self

Create a logger that does not log bodies.

pub fn with_body_logging(max_bytes: usize) -> Self

Create a logger that includes up to max_bytes of body content.

pub fn log_request(&self, ctx: &RequestContext)

Log an incoming request.

pub fn log_response(&self, ctx: &RequestContext, status: u16, body_bytes: usize)

Log an outgoing response.

pub fn format_request_line(ctx: &RequestContext) -> String

Format an incoming-request log line.

Output: "[{request_id}] {method} {path} from {client_id}"

pub fn format_response_line( ctx: &RequestContext, status: u16, elapsed_ms: u64, ) -> String

Format an outgoing-response log line.

Output: "[{request_id}] {status} in {elapsed_ms}ms"
