Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl<'a> UserDataBlock<'a>

pub fn data_records(&self) -> Option<DataRecords<'_>>

Returns an iterator over the variable data records in this block.

Fixed data structures, control messages, and encrypted payloads do not expose records. Decrypt an encrypted payload before parsing its records.

pub fn is_encrypted(&self) -> Option<bool>

pub fn variable_data_len(&self) -> usize

Returns the length of the variable data block (encrypted payload size)
