# Struct Mark Event

> ATOF point-in-time mark event.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi`.

<pre />

ATOF point-in-time mark event.

## Fields

### `base: BaseEvent`

Shared ATOF envelope.

### `category: Option<EventCategory>`

Optional semantic category for the checkpoint.

### `category_profile: Option<CategoryProfile>`

Optional category-specific typed fields.

## Implementations

### `impl MarkEvent`

<pre />

#### `builder`

<pre />

Create a builder for building `MarkEvent`. On the builder, call `.category(...)`(optional), `.category_profile(...)`(optional) to set the values of the fields. Finally, call `.build()` to create the instance of `MarkEvent`.

### `impl MarkEvent`

<pre />

#### `new`

<pre />

Construct a mark event from a base envelope and optional category data.

##### Parameters

##### Returns

A [`MarkEvent`](/reference/api/rust-library-reference/nemo-relay/api/event/struct-markevent) containing the provided fields.
