Struct UpdateTokenMetadataField 

pub struct UpdateTokenMetadataField {
    pub field: TokenMetadataField,
    pub value: String,
}

Updates a field in a token-metadata account.

The field can be one of the required fields (name, symbol, URI), or a totally new field denoted by a “key” string.

By the end of the instruction, the metadata account must be properly resized based on the new size of the TLV entry.

• If the new size is larger, the program must first reallocate to avoid overwriting other TLV entries.
• If the new size is smaller, the program must reallocate at the end so that it’s possible to iterate over TLV entries

Fields

field: TokenMetadataField

Field to update in the metadata.

value: String

Value to write for the field.

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

impl Clone for UpdateTokenMetadataField

fn clone(&self) -> UpdateTokenMetadataField

Returns a duplicate of the value.

impl Debug for UpdateTokenMetadataField

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

Formats the value using the given formatter.

impl PartialEq for UpdateTokenMetadataField

fn eq(&self, other: &UpdateTokenMetadataField) -> 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.
