Enum mz_repr::adt::char::CharWhiteSpace

enum CharWhiteSpace {
    Trim,
    Pad,
}

Controls how to handle trailing whitespace at the end of bpchar data.

Variants

Trim

Trim all whitespace from strings, which is appropriate for storing bpchar data in Materialize. bpchar data is stored in datums with its trailing whitespace trimmed to enforce the same equality semantics as PG, while also allowing us to bit-wise equality on rows.

Pad

Blank pad strings, which is appropriate for returning bpchar data out of Materialize.

Implementations

impl CharWhiteSpace

fn process_str(&self, s: &str, length: Option<usize>) -> String

Trait Implementations

impl Clone for CharWhiteSpace

fn clone(&self) -> CharWhiteSpace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CharWhiteSpace

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

Formats the value using the given formatter.

impl Hash for CharWhiteSpace

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 Ord for CharWhiteSpace

fn cmp(&self, other: &CharWhiteSpace) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CharWhiteSpace

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

impl PartialOrd for CharWhiteSpace

fn partial_cmp(&self, other: &CharWhiteSpace) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
