Struct StaticLayout 

pub struct StaticLayout { /* private fields */ }

A precomputed layout for a type whose encoded BSATN and BFLATN lengths are both known constants, enabling fast BFLATN <-> BSATN conversions.

Implementations

impl StaticLayout

pub fn for_row_type(row_type: &RowTypeLayout) -> Option<Self>

Construct a StaticLayout for converting BFLATN rows of row_type <-> BSATN.

Returns None if row_type contains a column which does not have a constant length in BSATN, either a [VarLenType] or a SumTypeLayout whose variants do not have the same “live” unpadded length.

Trait Implementations

impl Clone for StaticLayout

fn clone(&self) -> StaticLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StaticLayout

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

Formats the value using the given formatter.

impl MemoryUsage for StaticLayout

fn heap_usage(&self) -> usize

The heap memory usage of this type. The default implementation returns 0.

impl PartialEq for StaticLayout

fn eq(&self, other: &StaticLayout) -> 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.
