Struct BodyWrap 

pub struct BodyWrap { /* private fields */ }

Immutable, always-progressing Base64 body wrapping policy.

Implementations

impl LineWrap

pub const fn try_new( line_width: usize, line_ending: LineEnding, ) -> Result<Self, LineWrapError>

Constructs a validated wrapping policy.

pub const fn line_width(self) -> NonZeroUsize

Returns the non-zero encoded body width.

pub const fn line_ending(self) -> LineEnding

Returns the separator inserted between body lines.

pub const fn checked_output_len(self, payload_len: usize) -> Option<usize>

Returns the exact wrapped size without a trailing line ending.

pub fn insert_into(self, payload: &[u8], output: &mut [u8]) -> Option<usize>

Inserts line endings into an already encoded Base64 body.

The destination is unchanged when it is too small or length arithmetic overflows. Successful output never has a trailing line ending.

pub fn payload_len(self, input: &[u8]) -> Option<usize>

Validates wrapped body layout and returns its unwrapped payload length.

Interior lines must have exactly the configured width. A final line may be shorter, and one final line ending is accepted for compatibility with body formats that terminate their last line.

pub fn copy_payload_into(self, input: &[u8], output: &mut [u8]) -> Option<usize>

Validates and copies a wrapped body without its line endings.

The destination is unchanged when layout validation fails or the destination is too small.
