Struct ChainFallback 

pub struct ChainFallback { /* private fields */ }

Chain fallback handler that tries multiple handlers in sequence.

Tries each handler in order until one returns a non-Fail result. If all handlers fail, returns the last Fail result.

Example

use forge_agent::workflow::tools::{ChainFallback, RetryFallback, SkipFallback};

let fallback = ChainFallback::new()
    .add(RetryFallback::new(3, 100))
    .add(SkipFallback::skip());

Implementations

impl ChainFallback

pub fn new() -> Self

Creates a new ChainFallback.

Example

use forge_agent::workflow::tools::ChainFallback;

let fallback = ChainFallback::new();

pub fn add(self, handler: impl FallbackHandler + 'static) -> Self

Adds a handler to the chain.

Arguments

• handler - Handler to add to the chain

Returns

Self for builder pattern chaining

Example

use forge_agent::workflow::tools::{ChainFallback, RetryFallback, SkipFallback};

let fallback = ChainFallback::new()
    .add(RetryFallback::new(3, 100))
    .add(SkipFallback::skip());

Trait Implementations
