Struct warpgrapher::engine::config::Configuration

pub struct Configuration {
    pub model: Vec<Type>,
    /* private fields */
}

Configuration for a Warpgrapher data model. The configuration contains the version of the Warpgrapher configuration file format, a vector of Type structures, and a vector of Endpoint structures.

Examples

  
let c = Configuration::new(1, Vec::new(), Vec::new());

Fields

model: Vec<Type>

A vector of Type structures, each defining one type in the data model

Implementations

impl Configuration

pub fn new(
    version: i32,
    model: Vec<Type>,
    endpoints: Vec<Endpoint>
) -> Configuration

Creates a new Configuration data structure with the version, Type vector, and Endpoint vector provided as arguments.

Examples

let c = Configuration::new(1, Vec::new(), Vec::new());

pub fn endpoints(&self) -> Iter<'_, Endpoint>

Returns an iterator over the Endpoint structs defining custom root endpoints in the GraphQL schema

Examples

let c = Configuration::new(1, Vec::new(), Vec::new());
for e in c.endpoints() {
    let _name = e.name();
}

pub fn types(&self) -> Iter<'_, Type>

Returns an iterator over the Type structs defining types in the GraphQL schema

Examples

let c = Configuration::new(1, Vec::new(), Vec::new());
for t in c.types() {
    let _name = t.name();
}

pub fn validate(&self) -> Result<(), Error>

Validates the Configuration data structure. Checks that there are no duplicate Endpoint or Type items, and that the Endpoint input/output types are defined in the model. Returns () if there are no validation errors.

Errors

Returns an Error variant ConfigItemDuplicated if there is more than one type or more than one endpoint that use the same name.

Returns an Error variant ConfigItemReserved if a named configuration item, such as an endpoint or type, has a name that is a reserved word, such as “ID” or the name of a GraphQL scalar type.

Example

let config = Configuration::new(1, Vec::new(), Vec::new());
config.validate();

pub fn version(&self) -> i32

Returns the version number of the configuration format used for the configuration

Examples

let c = Configuration::new(1, Vec::new(), Vec::new());

assert_eq!(1, c.version());
