Struct Schema 

pub struct Schema {
    pub name: String,
    pub columns: Vec<Column>,
}

Schema for a table (defined by =)

Fields

name: String

Table or schema name.

columns: Vec<Column>

Ordered column definitions.

Implementations

impl Schema

pub fn new(name: String) -> Self

Create an empty schema with the provided name.

pub fn with_columns(name: String, columns: Vec<Column>) -> Self

Create a schema from a prebuilt ordered column list.

pub fn add_column(&mut self, name: String, type_hint: TypeHint)

Append a column definition to the schema.

pub fn parse_definition(name: String, def: &str) -> Result<Self>

Parse schema definition like: “id%i name%s km%f active%b”

pub fn column_index(&self, name: &str) -> Option<usize>

Get column index by name

pub fn column(&self, idx: usize) -> Option<&Column>

Get column by index

pub fn len(&self) -> usize

Number of columns

pub fn is_empty(&self) -> bool

Check if schema is empty

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl PartialEq for Schema

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