Struct StringValue

pub struct StringValue<'a> {
    pub value: &'a str,
}

AST Node of a string value.

GraphQL has a number of escaped characters that are normalised away when parsing and hence this value is expected to not contain escaped characters. The strings in GraphQL can be compared to JSON Unicode strings. Reference

Fields

value: &'a str

Implementations

impl<'a> StringValue<'a>

pub fn new<S: AsRef<str>>(ctx: &'a ASTContext, str: S) -> Self

pub fn is_block(&self) -> bool

Determines whether a string should be printed as a block string rather than a regular single-line string.

Trait Implementations

impl<'a> Clone for StringValue<'a>

fn clone(&self) -> StringValue<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for StringValue<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for StringValue<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl<'a> From<StringValue<'a>> for Value<'a>

fn from(x: StringValue<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for StringValue<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for StringValue<'a>

fn eq(&self, other: &StringValue<'a>) -> 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<'a> PrintNode for StringValue<'a>

fn write_to_buffer(&self, level: usize, buffer: &mut dyn Write) -> Result

Write an AST node to a buffer implementing the Write trait.

fn print(&self) -> String

Print an AST Node to source text as a String allocated on the heap.

impl<'a> ValueFromNode<'a> for StringValue<'a>

fn to_json(self, _variables: Option<&Variables<'a>>) -> JSValue

Convert current StringValue Node to a serde_json::Value.

impl<'a> Copy for StringValue<'a>

impl<'a> Eq for StringValue<'a>

impl<'a> StructuralPartialEq for StringValue<'a>
