Struct Column 

pub struct Column {
    pub name: String,
    pub ty: String,
    pub nullable: bool,
    pub length: Option<i64>,
    pub precision: Option<i64>,
    pub scale: Option<i64>,
}

Metadata for one result column, from the query response rowtype.

Fields

name: String

Column name as Snowflake reported it.

ty: String

Lowercase Snowflake type tag (e.g. fixed, text, timestamp_ntz).

nullable: bool

Whether the column may be null.

length: Option<i64>

Declared length (text), when reported.

precision: Option<i64>

Declared precision (number), when reported.

scale: Option<i64>

Declared scale (number/time/timestamp), when reported.

Implementations

impl Column

pub fn type_label(&self) -> String

A compact, lowercase type label with parameters when reported (e.g. fixed(10,2), text(255), timestamp_ntz(9)).

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl Eq for Column

impl PartialEq for Column

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