Struct LocalDefinitions 

pub struct LocalDefinitions { /* private fields */ }

The 16-slot local-definition table.

Each Definition message stores itself at index local_mesg_num (0..=15), overwriting any previous occupant. Each Data message looks up its slot to learn how to parse its bytes.

At the start of a new chained FIT file (multi-FIT) the table must be fully cleared via Self::clear.

Implementations

impl LocalDefinitions

pub fn new() -> Self

Create an empty local-definition table.

pub fn get(&self, local_mesg_num: u8) -> Option<&MessageDefinition>

Borrow the definition stored in local_mesg_num’s slot, if any.

pub fn require( &self, local_mesg_num: u8, ) -> Result<&MessageDefinition, FitError>

Borrow or error with FitError::UndefinedLocalMesgNum.

pub fn set(&mut self, local_mesg_num: u8, def: MessageDefinition)

Install a definition, overwriting any prior occupant.

pub fn clear(&mut self)

Drop every slot. Required at chained-FIT boundaries.

pub fn occupied(&self) -> usize

Number of currently-occupied slots (≤ 16).
