Module base64 

base64 encoding and decoding.

This module provides base64 encoding/decoding using a 64-character alphabet. Both padded and unpadded variants are available.

Constants

PADDED

Padded base64 encoding (alias of STD).

RAW

Raw base64 encoding without padding.

STD

Standard base64 encoding with padding.

Functions

decode

Decodes base64 encoded bytes with padding.

decode_len

Returns the decoded output length for padded input.

decode_mut

Decodes base64 encoded bytes into a mutable buffer with padding.

decode_n

Decodes a fixed-size base64 array with padding.

decode_raw

Decodes base64 encoded bytes without padding.

decode_raw_len

Returns the decoded output length for unpadded input.

decode_raw_mut

Decodes base64 encoded bytes into a mutable buffer without padding.

decode_raw_n

Decodes a fixed-size base64 array without padding.

decode_writer

Creates a decoding writer that wraps an io::Write.\n\nThe writer buffers base64 encoded bytes with padding, decodes them, and writes the raw output to the inner writer.\n\n# Examples\n\n\nuse omp_core::base64;\nuse std::io::Write;\n\nlet mut output = Vec::new();\nlet encoded = base64::encode(b\"Hello\").into_vec();\nlet mut writer = base64::decode_writer(&mut output);\nwriter.write_all(&encoded).unwrap();\nwriter.flush().unwrap();\nassert_eq!(output, b\"Hello\");\n\n

decode_writer_raw

Creates a decoding writer for unpadded base64.\n\nThe writer buffers base64 encoded bytes without padding, decodes them, and writes the raw output to the inner writer.\n\n# Examples\n\n\nuse omp_core::base64;\nuse std::io::Write;\n\nlet mut output = Vec::new();\nlet encoded = base64::encode_raw(b\"Hello\").into_vec();\nlet mut writer = base64::decode_writer_raw(&mut output);\nwriter.write_all(&encoded).unwrap();\nwriter.flush().unwrap();\nassert_eq!(output, b\"Hello\");\n\n

encode

Encodes a byte slice to base64 with padding.

encode_len

Returns the encoded length including padding.

encode_mut

Encodes bytes into a mutable buffer with padding.

encode_n

Encodes a fixed-size byte array to base64 with padding.

encode_raw

Encodes a byte slice to base64 without padding.

encode_raw_len

Returns the encoded length without padding.

encode_raw_mut

Encodes bytes into a mutable buffer without padding.

encode_raw_n

Encodes a fixed-size byte array to base64 without padding.

encode_writer

Creates an encoding writer that wraps an io::Write.\n\nThe writer buffers raw bytes, encodes them to base64 with padding, and writes the encoded output to the inner writer.\n\n# Examples\n\n\nuse omp_core::base64;\nuse std::io::Write;\n\nlet mut output = Vec::new();\nlet mut writer = base64::encode_writer(&mut output);\nwriter.write_all(b\"Hello\").unwrap();\nwriter.flush().unwrap();\n\n

encode_writer_raw

Creates an encoding writer for unpadded base64.\n\nThe writer buffers raw bytes, encodes them to base64 without padding, and writes the encoded output to the inner writer.\n\n# Examples\n\n\nuse omp_core::base64;\nuse std::io::Write;\n\nlet mut output = Vec::new();\nlet mut writer = base64::encode_writer_raw(&mut output);\nwriter.write_all(b\"Hello\").unwrap();\nwriter.flush().unwrap();\n\n
