windows 上的 Rust 编译引用了不存在的 d: 驱动器
Rust compilation on windows referring to nonexistent d: drive
我尝试在 windows 中编译一个 Rust 项目，Rust 给出了错误的错误“磁盘没有 space”。请告诉我如何克服这个问题。
我注意到：我的笔记本电脑上没有 D: 驱动器，但此路径显示 d:
它来自哪里？

TLDR:
包含 d: 的路径与编译 Microsoft C 运行time 库的机器相关，与您的机器无关。它们与您遇到的错误无关。
您收到的错误是因为该程序试图在与您 运行 从中创建它的目录相同的卷中创建一个 200GB 的数据库，并且没有足够的 space.
您看到的错误来自 运行 编译程序，而不是编译程序。从输出中的这一行可以看出这一点：
Running `target\release\meilisearch.exe`
这一行指出了错误的位置：
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Heed(Io(Os { code: 112, kind: Other, message: "There is not enough space on the disk." }))', meilisearch-http\src\data.rs:69:27
具体来说：meilisearch-http\src\data.rs:69:27.
一些 google 侦探工作让我 Meilisearch where I found the offending line:
let db = Arc::new(Database::open_or_create(opt.db_path, db_opt).unwrap());
unwrap 函数调用正在触发恐慌。发生这种情况是因为函数 open_or_create 正在返回您最终看到的错误。
多一点搜索让我找到了这个项目的用户手册，其中描述了选项，特别是 Database Path 选项，它的默认值为 ./data。
在同一页面上，我看到了两个关于最大数据库大小的条目 (Max UDB Size and Max MDB size)。它们包括注释：
On Windows it is a fixed size that will be allocated on launch.
Because this allocates 100Gb on MeiliSearch launch, a Windows user can
use this option to decrease the size of the database.
好像有两个这样的数据库，每个100GB，是启动时分配的。似乎建议是，如果您不想从一开始就分配 200GB，则应将这些设置为较低的值。
所以：错误是说 space 包含 ./data 的卷（相对于您 运行 安装程序的目录）不足以分配 200GB 的数据库.
但这 'd:' 是从哪里来的？好吧，当您 运行 设置了环境变量 RUST_BACKTRACE 的程序时，它会显示 作为错误。堆栈跟踪向您显示了导致崩溃的每个函数调用，包括一些属于 C 运行time 库的部分（即，甚至不是生锈的一部分）。特别是这些：
48: invoke_main
at d:\agent\_work\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl:78
49: __scrt_common_main_seh
at d:\agent\_work\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl:288
是 Microsoft C 运行时间库的一部分。
回溯包括作为堆栈跟踪一部分的函数的文件和行号信息。但是此信息在编译时插入到库中，大概是在某些 Microsoft 构建服务器上。
给出的路径与编译 C 运行time 库的机器相关，与您的机器无关。
我尝试在 windows 中编译一个 Rust 项目，Rust 给出了错误的错误“磁盘没有 space”。请告诉我如何克服这个问题。
我注意到：我的笔记本电脑上没有 D: 驱动器，但此路径显示 d: 它来自哪里？

Panic in Arbiter thread.

TLDR:
包含
d:的路径与编译 Microsoft C 运行time 库的机器相关，与您的机器无关。它们与您遇到的错误无关。您收到的错误是因为该程序试图在与您 运行 从中创建它的目录相同的卷中创建一个 200GB 的数据库，并且没有足够的 space.
您看到的错误来自 运行 编译程序，而不是编译程序。从输出中的这一行可以看出这一点：
Running `target\release\meilisearch.exe`
这一行指出了错误的位置：
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Heed(Io(Os { code: 112, kind: Other, message: "There is not enough space on the disk." }))', meilisearch-http\src\data.rs:69:27
具体来说：meilisearch-http\src\data.rs:69:27.
一些 google 侦探工作让我 Meilisearch where I found the offending line:
let db = Arc::new(Database::open_or_create(opt.db_path, db_opt).unwrap());
unwrap 函数调用正在触发恐慌。发生这种情况是因为函数 open_or_create 正在返回您最终看到的错误。
多一点搜索让我找到了这个项目的用户手册，其中描述了选项，特别是 Database Path 选项，它的默认值为 ./data。
在同一页面上，我看到了两个关于最大数据库大小的条目 (Max UDB Size and Max MDB size)。它们包括注释：
On Windows it is a fixed size that will be allocated on launch. Because this allocates 100Gb on MeiliSearch launch, a Windows user can use this option to decrease the size of the database.
好像有两个这样的数据库，每个100GB，是启动时分配的。似乎建议是，如果您不想从一开始就分配 200GB，则应将这些设置为较低的值。
所以：错误是说 space 包含 ./data 的卷（相对于您 运行 安装程序的目录）不足以分配 200GB 的数据库.
但这 'd:' 是从哪里来的？好吧，当您 运行 设置了环境变量 RUST_BACKTRACE 的程序时，它会显示

是 Microsoft C 运行时间库的一部分。
回溯包括作为堆栈跟踪一部分的函数的文件和行号信息。但是此信息在编译时插入到库中，大概是在某些 Microsoft 构建服务器上。
