encode_rs_transcode

此库允许您轻松在写入器中进行文本转码。

转码由 encoding_rs 执行，此库仅提供了一个简单的构建器，以便与外部写入器轻松使用。

用例

• 以特定格式写入文件（例如，使用 csv crate）写入 CSV 文件

示例

extern crate csv;
use std::fs::File;
use encoding_rs_transcode::{encoding_rs::WINDOWS_1252, TranscoderBuilder};

fn main() {
    // Create a file writer
    let file = File::create("test.csv").unwrap();

    // Create a transcoder that'll transcode the input to WINDOWS_1252
    let transcoder_writer = TranscoderBuilder::new()
    //  .from_encoding(UTF_8) // implied by new()
        .to_encoding(WINDOWS_1252)
        .build_writer(file);

    // Create a CSV writer
    let mut csv_writer = csv::Writer::from_writer(transcoder_writer);
    // Write to the CSV file
    csv_writer.write_record(["foo", "bar"]).unwrap();
    csv_writer.write_record(["aceio", "àcéîö"]).unwrap();

    // The CSV file will now be encoded in WINDOWS_1252, without the CSV crate ever
    // aknowledging the final encoding.
    // This can be applied to any writer implementing the `Write` trait.
