Struct serde_gff::de::Deserializer

pub struct Deserializer<R: Read + Seek> { /* private fields */ }

Структура для поддержки чтения GFF файлов в экосистеме serde

Implementations

impl<R: Read + Seek> Deserializer<R>

pub fn new(reader: R) -> Result<Self>

Создает десериализатор для чтения GFF файла из указанного источника данных с использованием кодировки UTF-8 для декодирования строк и генерацией ошибки в случае, если декодировать набор байт, как строку в этой кодировке, не удалось.

Параметры

• reader: Источник данных для чтения файла

Ошибки

В случае, если не удалось прочитать заголовок GFF файла – например, он слишком короткий

pub fn with_encoding(
    reader: R,
    encoding: EncodingRef,
    trap: DecoderTrap
) -> Result<Self>

Создает десериализатор для чтения GFF файла из указанного источника данных с использованием указанной кодировки для декодирования строк.

Параметры

• reader: Источник данных для чтения файла
• encoding: Кодировка для декодирования символов в строках
• trap: Способ обработки символов в строках, которые не удалось декодировать с использованием выбранной кодировки

Ошибки

В случае, если не удалось прочитать заголовок GFF файла – например, он слишком короткий
