本文整理了Java中io.airlift.slice.Slice.toStringAscii()方法的一些代码示例，展示了Slice.toStringAscii()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Slice.toStringAscii()方法的具体详情如下：
包路径：io.airlift.slice.Slice
类名称：Slice
方法名：toStringAscii

Slice.toStringAscii介绍

[英]Decodes the contents of this slice into a string using the US_ASCII character set. The low order 7 bits if each byte are converted directly into a code point for the string.
[中]使用US_ASCII字符集将该片段的内容解码为字符串。如果每个字节直接转换为字符串的代码点，则为低阶7位。
