    Path,
    Vector {
        element_type: String,
        dimension: Option<u32>,
    },

Implementations

impl LogicalType

pub fn from_legacy_str(s: &str) -> Self

Parse the legacy string representation used in pre-0.3 plans.

pub fn as_legacy_str(&self) -> Option<&str>

Serialize to the legacy string representation for cross-version compatibility.

Trait Implementations

impl Clone for LogicalType

fn clone(&self) -> LogicalType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogicalType

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

Formats the value using the given formatter.

impl Default for LogicalType

fn default() -> LogicalType

Returns the “default value” for a type.

impl PartialEq for LogicalType

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