Struct ExecutionHints 

pub struct ExecutionHints { /* private fields */ }

Collection of execution hints for a protocol.

Maps operation paths to their execution hints. Operations without explicit hints use default behavior (sequential, all responses required).

Implementations

impl ExecutionHints

pub fn new() -> ExecutionHints

Create an empty hints collection.

pub fn for_role(role: impl Into<String>) -> ExecutionHints

Create hints for a specific role.

pub fn role(&self) -> Option<&str>

Get the role this hints collection is for.

pub fn insert(&mut self, path: OperationPath, hints: OperationHints)

Insert hints for an operation path.

pub fn get(&self, path: &OperationPath) -> Option<&OperationHints>

Get hints for an operation path.

pub fn is_parallel(&self, path: &OperationPath) -> bool

Check if an operation should use parallel execution.

pub fn min_responses(&self, path: &OperationPath) -> Option<u32>

Get the minimum responses requirement for an operation.

pub fn is_ordered(&self, path: &OperationPath) -> bool

Check if an operation should preserve ordering.

pub fn is_empty(&self) -> bool

Check if there are any hints.

pub fn len(&self) -> usize

Get the number of hints.

pub fn iter(&self) -> impl Iterator<Item = (&OperationPath, &OperationHints)>

Iterate over all hints.

pub fn merge(&self, other: &ExecutionHints) -> ExecutionHints

Merge with another hints collection.

pub fn extract_from_protocol(protocol: &Protocol) -> ExecutionHints

Extract execution hints from a Protocol tree.

Walks the protocol and extracts @parallel, @min_responses, and @ordered annotations into an ExecutionHints collection.

Trait Implementations

Performs copy-assignment from source.

impl Debug for ExecutionHints

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl Default for ExecutionHints

fn default() -> ExecutionHints

Returns the “default value” for a type.
