Struct ColumnMeta 

pub struct ColumnMeta {
    pub name: String,
    pub ty: Type,
    pub marked_primary_key: bool,
    pub has_database_default: bool,
    pub ident: Ident,
    pub skip: bool,
    pub rust_default: Option<String>,
    pub join: Option<Join>,
    pub json: bool,
}

All the metadata we can capture about a column

Fields

name: String

Name of the column in the database

ty: 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

ident: Ident

Identifier used in Rust to refer to the column

skip: bool

rust_default: Option<String>

join: Option<Join>

json: bool

Implementations

impl ColumnMeta

pub fn is_default(&self) -> bool

pub fn from_fields<'a>(fields: impl Iterator<Item = &'a Field>) -> Vec<Self>

pub fn from_syn(ident: &Ident, ty: &Type) -> Self

pub fn is_join(&self) -> bool

pub fn is_join_one(&self) -> bool

pub fn is_join_many(&self) -> bool

pub fn is_option(&self) -> bool

pub fn is_json(&self) -> bool

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

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

pub fn joined_model(&self) -> TokenStream
