高级写入操作 trait

Required Methods§

Source

fn shift_datetime<P: AsRef<Path>>( &self, path: P, offset: DateTimeOffset, ) -> Result<()>

偏移日期时间标签

§示例
use exiftool_rs_wrapper::ExifTool;
use exiftool_rs_wrapper::advanced::AdvancedWriteOperations;
use exiftool_rs_wrapper::advanced::DateTimeOffset;

let exiftool = ExifTool::new()?;

// 将所有日期时间增加 1 天 2 小时
exiftool.shift_datetime("photo.jpg", DateTimeOffset::new().days(1).hours(2))?;
Source

fn shift_specific_datetime<P: AsRef<Path>>( &self, path: P, tag: TagId, offset: DateTimeOffset, ) -> Result<()>

仅偏移特定日期时间标签

Source

fn numeric_operation<P: AsRef<Path>>( &self, path: P, tag: TagId, operation: NumericOperation, ) -> Result<()>

数值运算

Source

fn append_string<P: AsRef<Path>>( &self, path: P, tag: TagId, suffix: &str, ) -> Result<()>

字符串追加

Source

fn write_if<P: AsRef<Path>, F>( &self, path: P, condition: &str, builder_fn: F, ) -> Result<()>
where F: FnOnce(WriteBuilder<'_>) -> WriteBuilder<'_>,

条件写入

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
