Implementations

impl DataDictionary

pub fn parse(text: &str) -> Result<Self>

pub async fn load(path: impl AsRef<Path>) -> Result<Self>

pub fn merged_with_app(self, app: &DataDictionary) -> DataDictionary

Combine a FIXT transport dictionary (header/trailer/admin messages) with an application dictionary (app messages and fields) into one effective dictionary for validation.

pub fn canonicalize_body(&self, msg: &mut Message)

Reorder a message body into the canonical form the reference engines produce: top-level fields ascending by tag, with each repeating-group block kept intact (in received/insertion order) under its counter tag.

pub fn group_template( &self, msg_type: &str, counter: Tag, ) -> Option<GroupTemplate>

A ready-made GroupTemplate for reading a repeating group of this message type (top-level groups only).

pub fn validate( &self, msg: &Message, settings: &ValidationSettings, ) -> Result<(), RejectError>

Validate a parsed message. Returns the reject that should be sent when it fails.
