Metadata provides generic information about the specifc location of the span! or event! call on the wasm-side.

Fields

name: Vec<u8>

target: Vec<u8>

The given target to event!/span! – or module-name, &'static str converted to bytes

level: WasmLevel

The level of this entry

file: Vec<u8>

The file this was emitted from – useful for debugging; &'static str converted to bytes

line: u32

The specific line number in the file – useful for debugging

module_path: Vec<u8>

The module path; &'static str converted to bytes

is_span: bool

Whether this is a call to span! or event!

fields: WasmFields

The list of fields specified in the call
