Struct ModelState 

pub struct ModelState {
    pub name: String,
    pub table: String,
    pub fields: Vec<FieldState>,
    pub indexes: Vec<IndexState>,
    pub constraints: Vec<ConstraintState>,
}

Snapshot of one model (or a synthesized M2M join table).

Fields

name: String

Rust type name (User); also the migration model name.

table: String

Table name.

fields: Vec<FieldState>

Concrete columns in declaration order.

indexes: Vec<IndexState>

Named indexes.

constraints: Vec<ConstraintState>

Table constraints.

Implementations

impl ModelState

pub fn from_meta(meta: &ModelMeta) -> Option<Self>

Copy a managed ModelMeta. Returns None when managed is false.

pub fn field(&self, name: &str) -> Option<&FieldState>

Field by Rust name.

pub fn field_mut(&mut self, name: &str) -> Option<&mut FieldState>

Mutable field by Rust name.

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

Field by column name.

pub fn pk(&self) -> Option<&FieldState>

Primary-key field, if declared.

pub fn index(&self, name: &str) -> Option<&IndexState>

Named index.

pub fn constraint(&self, name: &str) -> Option<&ConstraintState>

Named constraint.
