Struct ormlite_attr::ColumnMetadata

pub struct ColumnMetadata {
    pub column_name: String,
    pub column_type: Type,
    pub marked_primary_key: bool,

}

All the metadata we can capture about a column

Fields

column_name: String

Name of the column in the database

column_type: Type

marked_primary_key: bool

Only says whether the primary key is marked (with an attribute). Use table_metadata.primary_key to definitively know the primary key.

has_database_default: bool

identifier: Ident

Identifier used in Rust to refer to the column

many_to_one_key: Option<Ident>

many_to_many_table: Option<Path>

one_to_many_foreign_key: Option<Path>

Implementations

impl ColumnMetadata

pub fn builder() -> ColumnMetadataBuilder

pub fn is_join(&self) -> bool

pub fn joined_struct_name(&self) -> Option<String>

We expect this to only return a Model of some kind.

pub fn joined_path(&self) -> Option<&Path>

Whatever is inside the Join. We’re expecting a Model or a Vec<Model>.
