Struct StepExecutionResult 

pub struct StepExecutionResult {
    pub step_number: u32,
    pub success: bool,
    pub data: Option<Value>,
    pub error: Option<String>,
    pub duration_ms: u64,
}

Represents a step result from execution

Contains the outcome of executing a single saga step, including:

• Whether execution succeeded or failed
• Result data if successful (entity with key fields and updated values)
• Error details if failed
• Execution metrics (duration)

The result data is stored and available for subsequent steps to reference via result chaining.

Fields

step_number: u32

Step number that executed (1-indexed)

success: bool

Whether step succeeded (true) or failed (false)

data: Option<Value>

Result data if successful

Contains:

• __typename: Entity type
• Key fields (id, etc.)
• Mutation output fields
• Timestamps

error: Option<String>

Error message if failed

Includes:

• Error type (timeout, network, mutation failed, etc.)
• Subgraph context
• Suggestion for resolution

duration_ms: u64

Execution duration in milliseconds

Measured from step start to completion (or failure) Useful for performance monitoring
