Types ¶

type BuildTraceEntryFunc ¶

type BuildTraceEntryFunc func(context.Context, *ent.BuildTraceEntryMutation) (ent.Value, error)

The BuildTraceEntryFunc type is an adapter to allow the use of ordinary function as BuildTraceEntry mutator.

func (BuildTraceEntryFunc) Mutate ¶

func (f BuildTraceEntryFunc) Mutate(ctx context.Context, m ent.Mutation) (ent.Value, error)

The BuildTraceSignatureFunc type is an adapter to allow the use of ordinary function as BuildTraceSignature mutator.

func (BuildTraceSignatureFunc) Mutate ¶

func (f BuildTraceSignatureFunc) Mutate(ctx context.Context, m ent.Mutation) (ent.Value, error)

Mutate calls f(ctx, m).

type Chain ¶

type Chain struct {
	// contains filtered or unexported fields
}

Chain acts as a list of hooks and is effectively immutable. Once created, it will always hold the same set of hooks in the same order.

func NewChain ¶

func NewChain(hooks ...ent.Hook) Chain

NewChain creates a new chain of hooks.

func (Chain) Append ¶

func (c Chain) Append(hooks ...ent.Hook) Chain

Append extends a chain, adding the specified hook as the last ones in the mutation flow.

func (Chain) Extend ¶

func (c Chain) Extend(chain Chain) Chain

Extend extends a chain, adding the specified chain as the last ones in the mutation flow.

func (Chain) Hook ¶

func (c Chain) Hook() ent.Hook

Hook chains the list of hooks and returns the final hook.

type ChunkFunc ¶

type ChunkFunc func(context.Context, *ent.ChunkMutation) (ent.Value, error)

Mutate calls f(ctx, m).

type Condition ¶

type Condition func(context.Context, ent.Mutation) bool

Condition is a hook condition function.

func And ¶

func And(first, second Condition, rest ...Condition) Condition

And groups conditions with the AND operator.

func HasAddedFields ¶

func HasAddedFields(field string, fields ...string) Condition

HasAddedFields is a condition validating `.AddedField` on fields.

func HasClearedFields ¶

func HasClearedFields(field string, fields ...string) Condition

HasClearedFields is a condition validating `.FieldCleared` on fields.

func HasFields ¶

func HasFields(field string, fields ...string) Condition

HasFields is a condition validating `.Field` on fields.

func HasOp ¶

func HasOp(op ent.Op) Condition

HasOp is a condition testing mutation operation.

func Not ¶

func Not(cond Condition) Condition

Not negates a given condition.

func Or ¶

func Or(first, second Condition, rest ...Condition) Condition

Or groups conditions with the OR operator.
