file_indexing

用于快速且内存高效地编辑文件的库

crate

extern crate file_indexing;

删除文件行

file_indexing::delete_line(file, 4).expect("error");

删除文件行 delete_line_with_capacity

file_indexing::delete_line_with_capacity(file, 4 , 1000).expect("error");

删除文件行 2 , 4 , 6

file_indexing::delete_line_macro!(file,2,4,6);

删除文件行 2 到 4

file_indexing::delete_line_macro!(file,2 => 4);

读取行

println!("{}",file_indexing::read_line_index(file, 1).expect("error"));

带有容量的读取行

println!("{}",file_indexing::read_line_index_with_capacity(file, 1,1000).expect("error"));

读取行宏

println!("{}",file_indexing::read_line_index_macro!(file, 2));

读取行 2 和 5

println!("{}",file_indexing::read_line_index_macro!(file, 2 , 5));

读取行 2 到 4

println!("{}",file_indexing::read_line_index_macro!(file, 2 => 4));

替换行

file_indexing::replase_line(file, "pengganti", 2).expect("error");

替换行 _with_capacity

file_indexing::replase_line_with_capacity(file, "pengganti", 2 ,1000).expect("error");

替换行 2 , 3

file_indexing::replase_line_macro!(file,"pengganti\n",2,"pengganti\n",3);

弹出行

file_indexing::pop(file).expect("erro");

推入行

file_indexing::pust(file, "pust\n").expect("erro");

带有容量的推入行

file_indexing::pust_with_capacity(file, "pust\n",1000).expect("erro");

长度

file_indexing::len(file).expect("erro");

旋转

file_indexing::rotate(file, 1000).expect("erro");

带有容量的旋转

file_indexing::rotate_with_capacity(file, 1000 ,1000).expect("erro");
