impl Query

async fn api_version(&self, _: &Context<'_>) -> Result<&'static str>

Returns the API version. It is like a “greet” function

Returns all the users. It is restricted to admins only.

Request example:

curl http://localhost:8000/graphql
-H 'authorization: Bearer ***'
-H 'content-type: application/json'
-d '{"query":"{users(limit: 2) { id, email, password, name, address, isAdmin }}"}'

async fn user<'ctx>( &self, ctx: &Context<'ctx>, id: i32, ) -> Result<User, AppError>

-H 'authorization: Bearer ***'
-H 'content-type: application/json'
-d '{"query":"{user(id: 1) { id, email, password, name, address, isAdmin }}"}'

async fn positions<'ctx>( &self, ctx: &Context<'ctx>, moving_activity: Option<Vec<MovingActivity>>, limit: Option<i64>, offset: Option<i64>, ) -> Result<Option<Vec<Position>>, AppError>

Returns all the positions. It is restricted to admins only.

Request example:

curl http://localhost:8000/graphql
-H 'authorization: Bearer ***'
-H 'content-type: application/json'
-d '{"query":"{positions(movingActivity: IN_VEHICLE) {id, userId, createdAt, latitude, longitude, movingActivity}}"}'

async fn alerts<'ctx>( &self, ctx: &Context<'ctx>, id: Option<i32>, limit: Option<i64>, offset: Option<i64>, ) -> Result<Option<Vec<Alert>>, AppError>

Returns all the positions

Request example:

curl http://localhost:8000/graphql
-H 'authorization: Bearer ***'
-H 'content-type: application/json'
-d '{"query":"{alerts(id: 12) {id, userId, createdAt, area, areaLevel2, areaLevel3, text1, text2, text3, notifications {userId, latitude, longitude }}"}'

async fn notifications<'ctx>( &self, ctx: &Context<'ctx>, seen: Option<bool>, id: Option<i32>, alert_id: Option<i32>, limit: Option<i64>, offset: Option<i64>, ) -> Result<Option<Vec<Notification>>, AppError>

Returns all the notifications. They can be filtered by an alert id.
