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)

Mutate calls f(ctx, m).

type BuildTraceSignatureFunc 

type BuildTraceSignatureFunc func(context.Context, *ent.BuildTraceSignatureMutation) (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)

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.
