Trait DumpApi 

pub trait DumpApi<T: Types> {
    // Required method
    fn write_with<D>(&self, write_record: D) -> Result<(), Error>
       where D: FnMut(ChunkId, u64, Result<(Segment, WALRecord<T>), Error>) -> Result<(), Error>;

    // Provided methods
    fn write_to_string(&self) -> Result<String, Error> { ... }
    fn write<W: Write>(&self, w: W) -> Result<(), Error> { ... }
    fn write_display<W: Write>(&self, w: W) -> Result<(), Error>
       where WALRecord<T>: Display { ... }
}

A trait for dumping Raft log contents in a human-readable format.

Required Methods

fn write_with<D>(&self, write_record: D) -> Result<(), Error>

where D: FnMut(ChunkId, u64, Result<(Segment, WALRecord<T>), Error>) -> Result<(), Error>,

Writes the Raft log contents using a custom record writer function.

Arguments

• write_record - A function that writes individual log records. It takes:
  • ChunkId: The ID of the chunk containing the record
  • u64: The index of the record in its chunk
  • Result<(Segment, WALRecord<T>), io::Error>: The record data or error

Returns

• Ok(()) if writing succeeds
• Err(io::Error) if fails to read Raft-log or user provided callback returns an error

Provided Methods

fn write_to_string(&self) -> Result<String, Error>

Writes the Raft log contents to a String.

fn write<W: Write>(&self, w: W) -> Result<(), Error>

Writes the Raft log contents to the provided writer.

fn write_display<W: Write>(&self, w: W) -> Result<(), Error>

where WALRecord<T>: Display,

Writes the Raft log contents to the provided writer, using std::fmt::Display for record formatting.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
