Struct Record 

pub struct Record<'a> {
    pub fields: Vec<(String, Value)>,
    /* private fields */
}

Utility interface to build Value::Record objects.

Fields

fields: Vec<(String, Value)>

List of fields contained in the record. Ordered according to the fields in the schema given to create this Record object. Any unset field defaults to Value::Null.

Implementations

impl Record<'_>

pub fn new(schema: &Schema) -> Option<Record<'_>>

Create a Record given a Schema.

If the Schema is not a Schema::Record variant, None will be returned.

pub fn put<V>(&mut self, field: &str, value: V)

where V: Into<Value>,

Add a field to the Record.

NOTE: If the field name does not exist in the schema, the value is silently dropped.

pub fn get(&self, field: &str) -> Option<&Value>

Get the value for a given field name.

Returns None if the field is not present in the schema

Trait Implementations

impl<'a> Clone for Record<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Record<'a>

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

Formats the value using the given formatter.

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

fn from(value: Record<'a>) -> Self

Converts to this type from the input type.
