pub struct TableSchema {
    pub id: String,
    pub columns: Vec<TableColumnSchema>,
}

Parsed table schema JSON.

Fields

id: String

Stable schema/table id.

columns: Vec<TableColumnSchema>

Ordered table columns.

Implementations

impl TableSchema

pub fn from_package(package: &McdPackage, path: &str) -> Result<Self>

Parse a table schema from a package entry.

pub fn validate(&self, source: &str) -> Result<()>

Validate schema-level constraints.

pub fn columns_by_name(&self) -> IndexMap<&str, &TableColumnSchema>

Return a map keyed by column name.

pub fn has_column(&self, name: &str) -> bool

Return true when the schema contains a column.

pub fn column(&self, name: &str) -> Option<&TableColumnSchema>

Find a column by name.

Trait Implementations

impl Clone for TableSchema

fn clone(&self) -> TableSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableSchema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TableSchema

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TableSchema

fn eq(&self, other: &TableSchema) -> 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 Serialize for TableSchema

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
