False positive error on function or assosciate items

[chenyukang]

rust-analyzer version v0.3.2330, there is an error like this:

but I can jump to the definition of this function, means rust-analyzer actually knows function new_at, why is there still an error?

seems it comes from rustc output:

error[E0599]: no function or associated item named `new_at` found for struct `tentacle::runtime::Interval` in the current scope

note: if you're trying to build a new `tentacle::runtime::Interval`, consider using `tentacle::runtime::Interval::new` which returns `tentacle::runtime::Interval`

from the code there is no difference in accessibility:

There is no error or warning from cargo check.

Those are rustc errors, so they should show up in cargo check --all-targets (+ anything else you've configured in settings).

I run
cargo check --all-targets on the terminal command line, seems it does not show any error.

I open vscode logs for rust-analyzer, here is related configuration part:

{

...

runnables: {
    extraEnv: null,
    problemMatcher: [ '$rustc' ],
    askBeforeUpdateTest: true,
    command: null,
    extraArgs: [],
    extraTestBinaryArgs: [ '--show-output' ]
  },

...

check: {
    allTargets: true,
    command: 'check',
    extraArgs: [],
    extraEnv: {},
    features: [],
    ignore: [],
    invocationStrategy: 'per_workspace',
    noDefaultFeatures: null,
    overrideCommand: null,
    targets: null,
    workspace: true
  },

...

}

What's your rust-analyzer config in settings.json (user and workspace)?
