Struct InlineFragment

pub struct InlineFragment { /* private fields */ }

The InlineFragment type represents an inline fragment in a selection set that could be used as a field

InlineFragment: … TypeCondition? Directives? SelectionSet

Detailed documentation can be found in GraphQL spec.

Example

use apollo_encoder::{Field, InlineFragment, Selection, SelectionSet, TypeCondition};
use indoc::indoc;

let selections = vec![Selection::Field(Field::new(String::from("myField")))];
let mut selection_set = SelectionSet::new();
selections
    .into_iter()
    .for_each(|s| selection_set.selection(s));

let mut inline_fragment = InlineFragment::new(selection_set);
inline_fragment.type_condition(Some(TypeCondition::new(String::from("User"))));

assert_eq!(
    inline_fragment.to_string(),
    indoc! {r#"
        ... on User {
          myField
        }
    "#}
);

Implementations

impl InlineFragment

pub fn new(selection_set: SelectionSet) -> Self

Create an instance of InlineFragment

pub fn directive(&mut self, directive: Directive)

Add a directive.

pub fn type_condition(&mut self, type_condition: Option<TypeCondition>)

Set the inline fragment’s type condition.

Trait Implementations

impl Clone for InlineFragment

fn clone(&self) -> InlineFragment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InlineFragment

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

Formats the value using the given formatter.

impl Display for InlineFragment

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

Formats the value using the given formatter.

impl PartialEq for InlineFragment

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<InlineFragment> for InlineFragment

fn try_from(node: InlineFragment) -> 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.
