Field

Struct Field 

Source
pub struct Field<'cursor, 'de> { /* private fields */ }
Expand description

One object member. The value must be consumed with one of this type’s methods before requesting the next field.

Implementations§

Source§

impl<'de> Field<'_, 'de>

Source

pub fn name(&self) -> &str

Returns this member’s decoded field name.

Source

pub fn skip(self) -> Result<()>

Skips and validates this member’s value without constructing it.

§Errors

Returns an error for malformed JSON.

Source

pub fn raw(self) -> Result<RawJson<'de>>

Captures this member’s value without allocating.

§Errors

Returns an error for malformed JSON.

Source

pub fn string(self) -> Result<Cow<'de, str>>

Decodes this member as a string, borrowing when it has no escapes.

§Errors

Returns an error when the value is not a valid JSON string.

Source

pub fn deserialize<T: Deserialize<'de>>(self) -> Result<T>

Deserializes this member into a Serde type.

§Errors

Returns an error for malformed JSON or a type mismatch.

Source

pub fn object<T>( self, visitor: impl FnOnce(&mut Object<'_, 'de>) -> Result<T>, ) -> Result<T>

Visits this member as a nested object.

Unvisited nested fields are validated and skipped.

§Errors

Returns an error for malformed JSON or when the value is not an object.
