Enum apollo_encoder::Type_

pub enum Type_ {
    NonNull {
        ty: Box<Type_>,
    },
    List {
        ty: Box<Type_>,
    },
    NamedType {
        name: String,
    },
}

Convenience Type_ implementation used when creating a Field. Can be a NamedType, a NonNull or a List.

This enum is resposible for encoding creating values such as String!, [[[[String]!]!]!]!, etc.

Example

use apollo_encoder::{Type_};

let field_ty = Type_::NamedType {
    name: "String".to_string(),
};

let list = Type_::List {
    ty: Box::new(field_ty),
};

let non_null = Type_::NonNull { ty: Box::new(list) };

assert_eq!(non_null.to_string(), "[String]!");

Variants

NonNull

Fields

ty: Box<Type_>

Null inner type.

The Non-Null field type.

List

Fields

ty: Box<Type_>

List inner type.

The List field type.

NamedType

Fields

name: String

NamedType type.

The Named field type.

Trait Implementations

impl Clone for Type_

fn clone(&self) -> Type_

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Type_

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Type_

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Type_> for Type_

fn eq(&self, other: &Type_) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&Type> for Type_

type Error = FromHirError

The type returned in the event of a conversion error.

fn try_from(value: &Type) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<ListType> for Type_

fn try_from(node: ListType) -> Result<Self, Self::Error>

Create an apollo-encoder node from an apollo-parser one.

Errors

This returns an error if the apollo-parser tree is not valid. The error doesn’t have much context due to TryFrom API constraints: validate the parse tree before using TryFrom if granular errors are important to you.

type Error = FromError

The type returned in the event of a conversion error.

impl TryFrom<NamedType> for Type_

fn try_from(node: NamedType) -> Result<Self, Self::Error>

Create an apollo-encoder node from an apollo-parser one.

Errors

This returns an error if the apollo-parser tree is not valid. The error doesn’t have much context due to TryFrom API constraints: validate the parse tree before using TryFrom if granular errors are important to you.

type Error = FromError

The type returned in the event of a conversion error.

impl TryFrom<NonNullType> for Type_

fn try_from(node: NonNullType) -> Result<Self, Self::Error>

Create an apollo-encoder node from an apollo-parser one.

Errors

This returns an error if the apollo-parser tree is not valid. The error doesn’t have much context due to TryFrom API constraints: validate the parse tree before using TryFrom if granular errors are important to you.

type Error = FromError

The type returned in the event of a conversion error.

impl TryFrom<Type> for Type_

fn try_from(node: Type) -> Result<Self, Self::Error>

Create an apollo-encoder node from an apollo-parser one.

Errors

This returns an error if the apollo-parser tree is not valid. The error doesn’t have much context due to TryFrom API constraints: validate the parse tree before using TryFrom if granular errors are important to you.

type Error = FromError

The type returned in the event of a conversion error.
