Enum BlockLength 

pub enum BlockLength {
    Fixed(usize),
    Variable(usize),
}

Length of field printed by block

Variants

Fixed(usize)

Fixed length like numbers with padding

Variable(usize)

Variable length such as string descriptors - contained value is the heading (min) length

Implementations

impl BlockLength

pub fn len(self) -> usize

Get the length contained in Enum

pub fn is_empty(self) -> bool

Is the length zero

pub fn fixed_len(self) -> Option<usize>

Get the fixed length if [BlockLength::Fixed] else None

pub fn variable_len(self) -> Option<usize>

Get the variable length if [BlockLength::Variable] else None

Trait Implementations

impl Debug for BlockLength

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

Formats the value using the given formatter.

impl PartialEq for BlockLength

fn eq(&self, other: &BlockLength) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
