Struct ColumnSpec 

pub struct ColumnSpec {
    pub dimension: LasDimension,
    pub scalar: ScalarType,
    pub byte_width: Option<usize>,
}

Declares the LAS/COPC dimension and scalar type for a column.

Fields

dimension: LasDimension

scalar: ScalarType

byte_width: Option<usize>

For LasDimension::ExtraBytes, the fixed byte count stored for each point.

Implementations

impl ColumnSpec

pub const fn new(dimension: LasDimension, scalar: ScalarType) -> Self

pub const fn extra_bytes(byte_width: usize) -> Self

pub const fn default_for(dimension: LasDimension) -> Option<Self>

Returns the default fixed LAS/COPC scalar for dimension, when it has one.

pub const fn has_default_scalar(self) -> bool

Returns whether this specification has the canonical scalar for its dimension.

pub const fn matches_data(self, data: &ColumnData) -> bool

Returns whether data has the scalar type declared by this spec.

pub fn validate_data(self, data: &ColumnData) -> Result<()>

Validate the declared scalar against the supplied data.

pub fn validate_default_scalar(self) -> Result<()>

Validate that this spec uses the fixed LAS/COPC scalar for its dimension.

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

pub fn point_count_for_data(self, data: &ColumnData) -> Result<usize>

Trait Implementations

impl Clone for ColumnSpec

fn clone(&self) -> ColumnSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColumnSpec

impl Debug for ColumnSpec

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

Formats the value using the given formatter.

impl Eq for ColumnSpec

impl Hash for ColumnSpec

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColumnSpec

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