Struct ErasedFmt 

pub struct ErasedFmt { /* private fields */ }

Type-erased formatter captured at tool registration time.

This stores an optional formatting function that will be called at runtime to produce human-readable text from tool output. If None, the registry falls back to pretty-printed JSON.

pub const fn none() -> Self
