E0533: r##"
The `export_name` attribute was malformed.
Erroneous code example:
```compile_fail,E0533
#[export_name] // error: export_name attribute has invalid format
pub fn something() {}
fn main() {}
```
The `export_name` attribute expects a string in order to determine the name of
the exported symbol. Example:
```
#[export_name = "some_function"] // ok!
pub fn something() {}
fn main() {}
```
"##,
E0534: r##"
The `inline` attribute was malformed.
Erroneous code example:
```compile_fail,E0534
#[inline()] // error: expected one argument
pub fn something() {}
fn main() {}
```
The parenthesized `inline` attribute requires the parameter to be specified:
```ignore
#[inline(always)]
fn something() {}
// or:
#[inline(never)]
fn something() {}
```
Alternatively, a paren-less version of the attribute may be used to hint the
compiler about inlining opportunity:
```
#[inline]
fn something() {}
```
For more information about the inline attribute, read:
https://doc.rust-lang.org/reference.html#inline-attributes
"##,
E0535: r##"
An unknown argument was given to the `inline` attribute.
Erroneous code example:
```compile_fail,E0535
#[inline(unknown)] // error: invalid argument
pub fn something() {}
fn main() {}
```
The `inline` attribute only supports two arguments:
* always
* never
All other arguments given to the `inline` attribute will return this error.
Example:
```
#[inline(never)] // ok!
pub fn something() {}
fn main() {}
```
For more information about the inline attribute, https:
read://doc.rust-lang.org/reference.html#inline-attributes
"##,
E0536: r##"
The `not` cfg-predicate was malformed.
Erroneous code example:
```compile_fail,E0536
#[cfg(not())] // error: expected 1 cfg-pattern
pub fn something() {}
pub fn main() {}
```
The `not` predicate expects one cfg-pattern. Example:
```
#[cfg(not(target_os = "linux"))] // ok!
pub fn something() {}
pub fn main() {}
```
For more information about the cfg attribute, read:
https://doc.rust-lang.org/reference.html#conditional-compilation
"##,
E0537: r##"
An unknown predicate was used inside the `cfg` attribute.
Erroneous code example:
```compile_fail,E0537
#[cfg(unknown())] // error: invalid predicate `unknown`
pub fn something() {}
pub fn main() {}
```
The `cfg` attribute supports only three kinds of predicates:
* any
* all
* not
Example:
```
#[cfg(not(target_os = "linux"))] // ok!
pub fn something() {}
pub fn main() {}
```
For more information about the cfg attribute, read:
https://doc.rust-lang.org/reference.html#conditional-compilation
